BOSS KATANA Series | Combo Head Amplifier

KATANA-50 Gen3

Product Features
  • Compact and easy to carry
    Weighing just 12 kg, it's easy to carry from home to the studio, and can be set up in a small space without taking up much space.
  • Just the right amount of power
    The 50W output provides ample volume for home practice, band practice, and small live performances. The 0.5W mode keeps the volume low at home, but still provides ample volume when needed.
  • Basic functions are equivalent to those of higher-end models
    Although it's the most basic model in the series, it offers no compromises on sound quality or functionality, with six built-in amp types and over 6 effects. Despite its compact size, it's capable of producing the same sound as other models.

The 50 Gen3 is an entry-level model that offers an excellent balance of output, portability, and functionality. It's easy to use as a home amplifier and works well even in limited spaces. The Gen3 generation has also improved sound quality and expressiveness."Small but authentic"It is an ideal bike for beginners to intermediate riders.

Power Control allows you to enjoy powerful sound even late at night, and it can also produce sufficient volume when needed, making this a versatile combo that can cover everything from home practice to small-scale live performances.

Positive reviews
  • "It's light and easy to carry. At just under 12kg, it's lighter than a typical amplifier, so it's easy to carry up and down stairs and can be used casually in the studio for practice."
  • "The extensive built-in effects give you a wide range of sound creation, from clean to high gain. You can get a wide range of tones comparable to a multi-effects pedal, all in one unit."
  • "The volume is easy to adjust, so you can have it at a low volume at home or at a high volume in the studio. I'm happy that I can use this one unit for everything from practicing at home to small live performances."
Negative reviews
  • "The sound quality of this amplifier may be a matter of personal preference. Some people find the high notes a bit harsh and harsh on the ears, so it's not for everyone."
  • "The dedicated editor (BOSS TONE STUDIO) isn't very user-friendly. While you can fine-tune your sound on your PC or smartphone, the software's UI is a bit difficult to use."

KATANA-50 EX Gen3

Product Features
  • Stage-compatible expansion model
    Based on the standard 50 Gen3, this upgraded version offers enhanced live performance features. Its premium exterior features a gray/black woven grille, and its acoustics have been specially tuned to look great on stage.
  • Footswitches & Memory Expansion
    Compatible with the dedicated foot controller GA-FC (sold separately), it allows you to switch channels and control effects with your feet. The number of tone memories (storage tones) has also been doubled from 4 to 8, allowing you to instantly recall even more sound creations.
  • LINE OUT/Stereo expansion compatible
    The new line-out output uses cabinet IR, allowing you to send natural sound directly to a PA or recording station. It also supports the STEREO EXPAND function, which allows you to output stereo sound using two units of the same model, enabling you to create a stage sound that takes advantage of the spaciousness of the space.

The 50 EX Gen3 is a premium version of the KATANA-50 that's even more live-ready. Footswitch support allows hands-free operation, and memory expansion allows for smooth tone switching mid-song. Additionally, enhanced features like line out and stereo expansion dramatically improve usability for small live shows and stage performances.

Combined with specially tuned speakers and high-quality looks,"A 50W amplifier that looks great on stage"This is the perfect model for users who are not only practicing at home but also actively considering performing live.

Positive reviews
  • "It's convenient to be able to operate it at your feet! Thanks to GA-FC compatibility, it's easy to switch amp channels during a live performance, and the increase in memory slots to 8 makes it easy to use."
  • "I'm happy that it has a line out. The line output with a built-in mic makes recording and connecting to a PA easy, and when connected in stereo the sound spreads amazingly."
  • "The sound seems richer. Perhaps due to the dedicated speakers, the bass is rich and the cabinet resonates so well that it's hard to believe it's only 50W."
Negative reviews
  • "The price is a little higher than the regular 50. I wish it was a little more affordable, even though it's just for the added features, but it's still reasonable considering how many features it offers."
  • "It seems to be a little heavier (about 0.1 kg), but it feels about the same. However, because the exterior is more luxurious, I feel like I have to be more careful not to scratch it."

KATANA-100 Gen3

Product Features
  • Ample 100W output
    With a massive 100W output, it delivers presence that stands out even in band performances and medium- to large-scale live shows where loud volume is required. It also has ample clean headroom, allowing you to create sounds ranging from crunch to high gain with ease.
  • Effect loop included
    Another major feature of this model is the inclusion of a SEND/RETURN (effects loop) terminal, which allows you to connect your favorite external pedals or multi-effects units and use only the power amp section of the amp (a so-called return connection).
  • Versatile and uncompromising performance
    Whether you're practicing, rehearsing, recording, or performing live, this unit offers high-quality sound and reliable performance. It also includes all of the advanced features, such as eight tone memories and footswitch compatibility (GA-FC)."You can do anything with this one device"Its versatility is its appeal.

The 100 Gen3 is a powerful model designed for the stage. Compared to the 50W model, it offers ample volume and functionality, delivering a rich, full-bodied sound that won't get lost in a band ensemble. The effects loop allows for flexible use with external effects, so you can bypass the amp's preamp and use just the KATANA's power section with a multi-effects unit.

This is a versatile amp that can be used without compromise from practice to live performances, and is likely to be popular with intermediate and advanced players.

Positive reviews
  • "The sound is thick and can be played at high volumes with ease. The 100W of power gives a strong punch to both clean and distorted tones, so it won't get lost in a band."
  • "The effects loop is convenient! You can connect your favorite pedals and use only the power section of the amp, so you can get the most out of the sound of your multi-effects unit."
  • "An all-rounder that can handle anything. Perfect for home use or live performances, it's also practical with eight tone memories and footswitch compatibility."
Negative reviews
  • "It weighs about 15kg, so it's quite heavy, and requires a lot of strength to carry around. However, this is a standard weight for a combo of this class."
  • "The price is higher than the 50W model. It's reasonable considering the difference in functionality and performance, but it may be a bit of a hurdle for beginners to buy for practice."
BOSS

KATANA-100/212 Gen3

Product Features
  • Two-speaker spread
    This is an upgraded model with the same functionality as the Katana-100 Gen3, but equipped with two 12-inch speakers. While not stereo, the sound area is physically increased, filling the space with a wide sound field and deep sound.
  • Rich bass and sound pressure
    The large cabinet volume and dual speakers deliver sound with increased bass volume and punch. It feels like the sound is a whole lot thicker, even with the same 2W, and the rich sound is particularly appealing with clean and crunch notes.
  • Present-worthy stage sound
    Its strength is the powerful stage presence that only a 2x12" speaker can provide. The sound can easily travel far, even at outdoor live shows or in large venues, and it has a presence that rivals the rhythm section that forms the wall of the band. This is a model that can truly "fill the space with rich sound."

The 100/212 Gen3 is a model that further expands the sound of the Katana-100. The two speakers increase the width and depth of the sound, giving it outstanding presence on stage. As stated in the , it is possible to "fill the space with a richer sound," and it offers more room at high volumes and more powerful bass than the 2x1" model.

Although it weighs approximately 19.8 kg, the cabinet is on the heavy side, producing a rich tone that envelops multiple instruments even in clean modes. This makes it ideal for guitarists who often play at high volumes or who prioritize a powerful sound.

Positive reviews
  • "The sound is much thicker and wider. There's more bass than with a single guitar, and the clean, crisp sound seems to permeate the whole band."
  • "I'm very happy with the sound, which looks great on stage. The 2x12 gives me plenty of room for outdoor gigs, and really brings out the presence of my guitar."
  • "A luxurious combo with all the 100W features. It's big and heavy, but the air-shaking sound pressure is so satisfying even when playing it at home, so it's definitely worth the investment."
Negative reviews
  • "It's quite heavy at about 20kg, so you'll need to be prepared to transport it. It's not a problem if you plan to transport it by car, but it's a pain to carry it up and down stairs."
  • "Because of the incredible volume and sound pressure, it can be overwhelming at home. In an apartment building, it may not be able to perform at its full potential, so be careful not to let it go to waste."
BOSS

KATANA-HEAD Gen3

Product Features
  • Unique built-in speaker
    Although it's a 100W amp head, it also has a built-in 5-inch speaker that can output up to 30W on its own, allowing it to function as a practice monitor. You can easily use it as a standalone head at home, or connect an external cabinet for the full 100W on stage.
  • Equipped with new function "BLOOM"
    A new feature from Gen3 is BLOOM, which gives your sound a fuller, more resilient feel and a faster attack. Turning the switch on increases the projection and warmth of your sound, giving you a comfortable tube amp-like response in both clean and lead sounds.
  • Versatile inputs and outputs and MIDI compatibility
    In addition to SEND/RETURN (effects loop), it also features a MIDI IN terminal. Channel switching and effect control are also possible with an external MIDI pedal, allowing for flexible setup. This head amp has the expandability to meet the demands of professionals, from studio musicians to live performers.

The HEAD Gen3 is an amp head that combines portability with versatility. Its lightweight and compact size (approximately 8.8 kg) means it can produce a powerful 100W when connected to an external cabinet, and its own 5-inch speaker can output 30W of sound on its own.

The newly installed BLOOM function adds thickness and elasticity to the sound, giving it an even more tube-like feel than ever before. With a wide range of terminals, including MIDI, it's highly expandable, making it a high-performance head that can be used for everything from home practice to professional use.

Positive reviews
  • "The best thing about this is that you can get sound from just the head alone. Even if you want to practice a little in the middle of the night, you can get sound right away without needing a cabinet, and it produces a solid sound for a 5-inch guitar."
  • "The BLOOM function really makes the sound thicker. The clean sound is warmer, and when you add distortion it gives you a solid, fat lead tone that feels great."
  • "It has a wide range of input and output terminals, and is highly expandable. It's MIDI compatible, so I can switch channels with my MIDI foot switch, which made it easy to incorporate into my home-built system."
Negative reviews
  • "Even though it's just a head, it weighs about 9kg, so it's quite difficult to carry around. However, it's less than half the weight of a combo, so it's a convenient size for rehearsals and trips."
  • "The built-in speakers are convenient, but the sound quality is only good enough for a simple monitor. The bass is a bit lacking, so you should just connect it to a proper cabinet to get a full-fledged sound."

KATANA-ARTIST Gen3

Product Features
  • Custom WAZA Speaker
    This flagship combo amp features the original BOSS WAZA speaker (12-inch). Inspired by the classic vacuum tube amplifiers, this speaker delivers rich harmonic content and crisp response, delivering superb tone and response with any amp type.
  • Refined sound tuning
    The cabinet construction and internal circuitry have been meticulously tuned to deliver the same immersive sound quality as a high-end boutique amplifier. Combined with the newly added BLOOM function, the amplifier responds extremely naturally to the performer's nuances, delivering the highest level of sound quality in the studio or on stage.
  • Dedicated adjustments for all amplifier types
    To maximize the performance of the Artist's dedicated speakers and cabinets, each amp has been individually tuned for its sound. As a result, the tonal quality is outstanding in every mode, achieving a level of perfection that meets the demands of professionals.

The ARTIST Gen3 is the pinnacle of the KATANA series. Equipped with BOSS's signature WAZA speaker, it delivers exceptionally rich tone across the entire frequency range, from brown to clean. The cabinet and circuit design are specially optimized, and the Bloom function adds to the immersive, connected feel when playing.

Although it is large, weighing approximately 19 kg, many say that the sound it produces is "worth more than its price" and "worth more than its weight." This is the ideal stage amp for professional-minded guitarists and those who don't want to compromise on sound.

Positive reviews
  • "The brightness and power of the sound is on a completely different level. Perhaps thanks to the WAZA speaker, each note has more depth than other Katanas, making it feel like you're playing through a high-end tube amp."
  • "The quality is unparalleled. Each amp type has a carefully crafted sound that is easier to use and sounds better than a real tube amp. It's powerful enough to be used as a main amp by professionals."
  • "It doesn't break down even when you turn up the volume, but it still has a great sound even at low volumes. It's reliable and will always maintain the best tone, whether on stage or in the studio."
Negative reviews
  • "It weighs over 20kg, so it's difficult to carry around on your own. You'll need to transport it by car and be prepared for where to set it up. But for this sound quality, it's probably worth it."
  • "It's expensive and not very user-friendly. It's overkill for beginners and a luxury option even for intermediate players. But if you plan to use it for a long time, I think it's an amp worth the investment."

KATANA-ARTIST HEAD Gen3

Product Features
  • The best head in the series
    This is the pinnacle of the Katana series, alongside the Artist Gen3. Like the Artist combo, it features advanced sound tuning, delivering professional-grade sound quality, versatility, and performance capabilities. This flagship model is for players who prefer heads over combos.
  • Versatile cabinet connections
    With three speaker output jacks, you can stack up to one 3-ohm cabinet or two 8-ohm cabinets. This provides optimal power for any cabinet configuration, creating a powerful setup worthy of the stage. It's particularly impressive when combined with the dedicated Katana Cabinet 1 WAZA with two WAZA speakers.
  • The ultimate brown sound
    When paired with a WAZA speaker cabinet, it produces a superb brown sound reminiscent of a 60s British stack. Experience the rich overtones and resilient sound pressure that's hard to find anywhere else, the essence of the series.

The ARTIST HEAD Gen3 is the pinnacle of the Katana series. It boasts professional-grade sound quality and flexible connectivity, and can be used with multiple 8Ω/16Ω cabinets to create a powerful setup suitable for large-scale stages.

Its true value is revealed when combined with a WAZA speaker cabinet, delivering the ultimate "Katana sound" that the developers were aiming for. At approximately 12.4 kg, it's on the heavy side for a head, but its robustness and excellent sound, even when fully stacked, make it a popular model among discerning guitarists.

Positive reviews
  • "The sound is like the culmination of the Katana series! It sounds powerful no matter what cabinet you connect it to, and the combination with the WAZA 212 cabinet is particularly impressive."
  • "It can easily drive multiple cabinets, giving you peace of mind that you won't be short of sound in any venue. I think it's rare to find an amp that allows such flexibility in its head configuration."
  • "The sound has excellent clarity and presence, and it doesn't get lost in the band. It lives up to its reputation as a reliable, professional-grade head, and is a unit that can take center stage."
Negative reviews
  • "It's very expensive, so it's hard to get your hands on one... Considering the performance, it's a reasonable price, but it's also true that it's hard to justify using it for hobby purposes."
  • "The head alone weighs over 12kg, so it's quite difficult to transport. It's a flagship model, so it can't be helped, but it would be much easier to transport on tour if it were a little lighter."

BOSS KATANA Series | Compact Mini Amplifier for Home Use

KATANA-MINI

Product Features
  • Ultra-compact size
    It is very small, measuring just 24cm wide and weighing approximately 1.2kg, so it can be easily placed on a desk or in a small space at home.
  • Battery-powered
    It can run for approximately seven hours on six AA batteries, and can also be used with an AC adapter, so it can be used anywhere.
  • Authentic amp sound
    Utilizing BOSS amplifier design technology, the amp features three amplifier types: clean, crunch, and brown. Despite its compact size, it delivers solid sound quality.
  • Useful functions for practice
    Equipped with an AUX IN jack, you can connect a smartphone or audio player to practice along with the sound source. It also has a headphone/REC OUT jack, making it suitable for practicing at home or recording.

While the Katana-Mini was designed as a compact practice amp, it's more than just a toy; its greatest appeal is its ability to deliver high-quality BOSS sound. Battery-powered for easy use at the park or on the go, it offers three amp types to suit a wide range of genres, from rock to clean.

Furthermore, the headphone jack and AUX input make it ideal for quiet practice at home or playing at night. Because it's "small but produces a professional sound," it's popular not only as a practice amp for beginners, but also as a sub-amp for advanced players.

Positive reviews
  • "It's small but has a solid sound. I'm amazed that it can produce a brown sound in something this size."
  • "It's battery-powered, so you can play it anywhere. It's convenient to take it with you when camping or going on outdoor sessions."
  • "The AUX IN and headphone jack are convenient, so I've started practicing at home more often."
Negative reviews
  • "The bass is a bit thin. It's not powerful enough for band practice or other situations where you need a loud volume."
  • "The only effect is delay, so I wish there were more options to play around with."
BOSS
13,200 JPY(TAX+) (As of 2026:05 on March 16, 11 | According to Amazon)

KATANA-Mini X

Product Features
  • Palm-sized with 10W output
    The Katana-Mini (7W) model boasts a more powerful output than its predecessor, the Katana-Mini, with a rated output of 10W. Despite its compact size and light weight of just 29cm wide and 2.7kg, it produces a much louder sound than you'd expect. It's loud enough for practicing at home, or even playing in the park or outdoors.
  • 5-inch speaker and wooden cabinet
    The speakers have been enlarged from 4 inches to 5 inches, and the housing has been changed from a plastic to a wooden cabinet. This has resulted in a richer bass range and a more authentic sound than its size would suggest. It has been well received, with people saying, "It produces surprisingly solid sound despite its small size."
  • Built-in battery & Bluetooth compatible
    It now has a built-in rechargeable battery (approximately 10 hours of continuous use) and can be charged via USB-C, eliminating the need to replace batteries. It also features Bluetooth functionality, allowing you to jam along with music from your smartphone, and future app integration is planned. Completely cordless practice is now possible.
  • A variety of effects and functions
    The amp types have been expanded to three with two variations each (six sounds), and a three-band EQ and ten built-in effects have been added. The range of sound creation has been greatly expanded compared to the previous model, which only had a delay. Furthermore, the new model is packed with features, including a built-in tuner and headphone/recording outputs.


The KATANA-Mini X is an ultra-compact amplifier that can be used anywhere. Its portable size and built-in battery allow you to play at home or outdoors without needing a power source. The 5-inch speaker and wooden cabinet add depth to the sound, producing a robust sound that you wouldn't expect from a 10W amplifier.

Its Bluetooth compatibility lets you stream music from your smartphone for jamming, or you can practice quietly using the headphone jack, making it incredibly easy to use. This compact amp is the perfect companion for practice, and is a model that is popular with a wide range of users, from beginners to advanced users.

Positive reviews
  • "It's surprisingly small, but it has a great sound and is loud! The wooden cabinet gives it good bass, and it's more than enough for playing in a room."
  • "It has a built-in battery, so I can play anywhere. I love jamming with friends in the park, bringing my amp, and taking it to training camps."
  • "The number of effects has increased, making sound creation more fun. Compared to the previous Mini, which only had delay, you can now use modulation and reverb, so even with this size you can create elaborate sounds."
Negative reviews
  • "It's a shame that the price has gone up compared to the previous model, but it has double the functionality, so I guess that's understandable...it's still a good value, though."
  • "Even though it's 10W, it's still not powerful enough for a band. It's fine for practicing at home or using it alone on the road, but once you add drums it gets drowned out, so you have to be careful about what you use it for."
BOSS
24,200 JPY(TAX+) (As of 2026:05 on March 16, 11 | According to Amazon)

KATANA-Air EX

Product Features
  • Completely wireless play
    The included guitar wireless transmitter (WL-T) allows for cable-free connection between your guitar and amplifier. The freedom of being able to play in any position and location without the hassle of cables becomes addictive. Bluetooth functionality is also included, so you can stream music from your smartphone and jam along.
  • Amazing stereo sound
    Two built-in 5-inch stereo speakers deliver a powerful sound output of up to 2W in total (when using the AC adapter). The rich, spacious stereo sound you'd never expect from such a compact unit makes practicing at home even more enjoyable.
  • Diverse sound creation and convenient functions
    In addition to five amp types (including Acoustic), the Air EX also offers a bass mode. It also comes with over 5 built-in BOSS effects, and the BOSS Tone Studio app makes tone editing and management easy. It also features line out jacks (L/R) for recording and external output.

The Katana-Air EX is a next-generation amplifier that allows you to play wirelessly without cables. The ease of wireless connection, allowing you to instantly play with your guitar, is revolutionary, and some users report that it has dramatically increased the frequency of their practice sessions. Despite its compact size, the Katana-Air EX delivers powerful sound with 30W stereo output, providing sound quality and volume that is more than sufficient for a home amplifier.

The dedicated app allows you to freely control effects, and it even comes with a bass mode, making it a truly comprehensive product. As mentioned above, the price is significantly lower than the previous Waza-Air (wireless headphones), making it a highly popular model as an amp that dramatically improves your home practice environment.

Positive reviews
  • "The feeling of freedom from not being tied down by cords is amazing! I can play while moving around the room, or even practice lying on the sofa."
  • "It produces a great sound even at low volumes. I can practice at night with a powerful sound, and the stereo effect gives a sense of spaciousness, making it fun to play."
  • "It's convenient because it connects to your smartphone. You can play along with songs via Bluetooth, and you can even fine-tune the sound with the app, so you'll never get bored."
Negative reviews
  • "The battery life may be a little short. If you use the built-in battery (3 AA batteries or a dedicated battery pack), you'll need to charge it if you play for a long time, so you may end up having to connect the AC adapter."
  • "The price is a bit high (but that's understandable since it includes wireless technology), so beginners might be a little hesitant to buy it for practice purposes. However, considering the convenience, I'm very satisfied with it."

KATANA:GO

Product Features
  • Palm-sized headphone amplifier
    This ultra-compact amplifier is perfect for both guitar and bass. Simply plug it directly into your guitar's jack and connect headphones to play. Its sleek, palm-sized design weighs approximately 0.24 kg and measures 45 x 29 x 125 mm, delivering the high-quality sound you expect from BOSS.
  • Equipped with 3D sound "STAGE FEEL"
    In addition to the dynamic amp sound inherited from the Katana series, the amp also features surround sound technology unique to headphones. It delivers an immersive experience not possible with regular headphones, allowing you to experience the spaciousness of sound coming from a cabinet on stage, even at home. This is truly a high-performance amp that can be used anywhere.
  • Extensive effects and connections
    The Voicing amp features five guitar and bass modes and numerous built-in effects. Connect to the BOSS TONE STUDIO smartphone app via Bluetooth for wireless tone editing and practicing along with your smartphone's audio. Connect to a PC or smartphone via USB-C to use it as an audio interface for recording and streaming.

The KATANA:GO is a revolutionary gadget that fits in your pocket. Weighing just a few hundred grams, it packs amp, effects, and audio I/F functionality, allowing you to practice with powerful sound even late at night or on the go, all you need is headphones.

At just ¥16,500, it's about one-third the price of the previous WAZA-AIR series (around ¥5), making it a great bargain. It's rapidly gaining popularity as an innovative headphone amplifier that allows guitarists and bassists to practice quietly and play anywhere.


Positive reviews
  • "It's incredibly small, but it produces a professional sound! High-gain sounds like Brown are crisp and clear, and I never thought practicing with headphones could be this fun."
  • "The fact that it can also be used for bass is surprisingly impressive. As someone who plays both guitar and bass, I appreciate the fact that it can be used for both by simply switching modes, and the sound is well-crafted."
  • "The price is reasonable. The WAZA-AIR was too expensive for me, but this one is affordable at about 1.6 yen. Considering the performance, it's the best value for money."
Negative reviews
  • "Please note that this is designed for wired headphones, so it's not completely wireless (like the WAZA-AIR). However, you can use your favorite headphones."
  • "Because the body is light, it has a strong plastic feel. The control knobs also feel a bit cheap, and it doesn't have a luxurious feel. However, I think it is sturdy."

Summary: How to Choose from the Wide Variety of Katana Series

Points to consider when choosing
  • For beginners who want to keep the volume down while mainly using it at home, we recommend the easy-to-use Katana-Air EX or Katana-Mini X. If you want to practice quietly, the Katana:GO is also a good choice.
  • If you're considering band practice or live performances, a combo with at least 50W is a safe bet. The Katana-50/50EX is ideal for small-scale live performances and frequent studio practice, while the Katana-100/100/212 are ideal for more serious use.
  • For intermediate to advanced players or those aiming for professional use who are particular about sound quality, the ARTIST series with WAZA speakers and flexible headsets are a reliable ally. The ARTIST Gen3 in particular is said to be so perfect that once you try it, you'll be hooked.

I hope you can see that there is a wide variety of models, from entry-level models to flagship models, and even mini/headphone types.

Please use the information in this article and user reviews as a reference to choose the "KATANA" that best suits your needs.
