FRIEDMAN | Its origins and appeal

Background of the foundation

Dave Friedman is a legendary guitarist who has tuned and modified the gear of top guitarists such as Eddie Van Halen and Steve Stevens. In 2008, he founded an amplifier brand to pursue his passion for sound and technique.

At the time of its founding, the company was committed to hand-wiring, and its uncompromising standards were reflected in all circuit design and material selection. The resulting FRIEDMAN quickly gained attention as a brand dedicated to the pursuit of precision tone, earning the reputation of being "a Marshall that surpasses Marshall."

Brand design philosophy and commitment

The appeal of FRIEDMAN products lies in their ability to bring vintage tone back to modern times. Rooted in the Marshall Plexi and JTM45, they are designed to handle a wide range of gains, from low to high, while retaining the responsiveness and playing nuances of tube pedals.

The attention to detail is evident in every aspect of the product, including a unique master volume mechanism that keeps chords clear and distortion distinct even at maximum volume, and the use of high-grade parts designed to the millimeter.

FRIEDMAN is an amplifier that "only really shows its true potential when played on stage," and we are extremely particular about "maintaining an authentic sound quality even at low volume."

Not only flagship models like the BE-100 Deluxe, but also smaller models like the RUNT and Pink Taco share the same characteristic of not losing grain or overtones even at lower volumes. This means you can always experience the same FRIEDMAN tone, whether practicing in your living room or performing on an arena-sized stage.

FRIEDMAN | Main amplifier

Friedman / BE-100 Deluxe

Product Features
  • 3-channel circuit
    The three channels (clean, BE, HBE) can be switched via the front panel or footswitch. The Deluxe model adds independent gain and master to BE/HBE.
  • Plexi Roots Tone
    A thick, rich brown sound based on the 1968 Marshall "Plexi" circuit, with tight bass and delicate harmonics in the high range.
  • Rich volume range
    Friedman's unique master volume control allows for distortion even at high volumes while still maintaining a clear chord feel.

The BE-100 Deluxe is Freedman's flagship 100W hand-wired tube amplifier. Its wide-ranging sound, from clean tones to ultra-drive, delivers professional-grade sound for both studio and live performances.

The three channels each have different gain characteristics, and the Deluxe allows you to adjust the volume independently, making it suitable for a wide range of genres.High-quality transformers and a custom power supply deliver unmatched response.

Positive reviews
  • "The sound is incredibly thick and the resolution of each note is high. The Brown sound is present at any volume."
  • "The three channels can be separated, allowing for great freedom of playability, from clean to high gain."
  • "It has the warmth and clarity of a hand-wired amplifier, but can also produce heavy distortion. Ideal for professional use."
Negative reviews
  • "It's very heavy and difficult to carry. Care must be taken when setting it up."
  • "The price is high and it's hard to afford. Many people hesitate when they consider the cost performance."

Friedman / BE-100

Product Features
  • An evolved version of the vintage Plexi
    Based on a 1968 Marshall Plexi, this brown sound is tuned by Dave Friedman.
  • Equipped with BE & HBE modes
    You can freely switch between crunch and high gain. HBE delivers even thicker, higher gain.
  • Three-dimensional, well-balanced tone
    It maintains the separation of chords while combining rich overtones and tight low end.
  • Professional Construction
    Hand-wired and featuring a custom transformer, this amplifier is used on stage by top guitarists around the world.

The Friedman BE-100 is the brand's flagship amp and the culmination of Dave Friedman's "modified Marshall" sound. Based on the vintage Plexi, it's also compatible with modern high-gain amplifiers, delivering exceptionally high-quality sound across the entire range of clean, crunch, and high-gain tones.

The BE channel's sound, known as the "brown sound," is particularly appealing, with its thick overtones and tight low end. The reason it has been loved by professional guitarists for many years is because of its "ease of creating sounds that can be used immediately on stage."

Positive reviews
  • "This is the ultimate modified Marshall. It strikes a perfect balance between vintage and modern."
  • "The BE channel handles lead, and the HBE handles everything from modern metal. This one unit can handle all genres."
  • "Even when playing chords, each note resonates without being crushed. It also sounds surprisingly clear when recording."
Negative reviews
  • "The controls are simpler, but the flexibility is less than Deluxe."
  • "The size and weight make it impractical for home use."

Friedman / Dirty Shirley 40W

Product Features
  • Vintage Rock Tone
    Designed to replicate the sound of British amps from the 60s and 70s (especially the Marshall JTM45), it delivers classic high-gain distortion.
  • Simple configuration
    The single channel (Gain, Volume, 3-band EQ, Gain selector switch) provides excellent operability. The flexibility to transition to a clean sound by simply turning down the guitar's volume knob is also provided.
  • 5881 (6L6) power tube
    Equipped with two American 5881 (modified 6L6) amplifiers, it delivers a mild yet powerful low end and deep distortion. It also has an effects loop.

The Dirty Shirley is a 40W head amp for guitarists who aspire to classic rock. It can cover everything from warm clean tones to bluesy overdrive, and excels at bringing that old-school British rock flavor to your sound.

It is particularly notable for its fat, sizzling distortion when the gain is turned up, and like the original Marshall, the amount of distortion is easy to control with the playing volume. Although the distortion sound is fat, turning down the clean volume returns it to a clean, crisp sound, making it useful at a wide range of volumes.

Positive reviews
  • "It has the fat sound of an old Marshall. It's great that the bass remains solid even when driven."
  • "It's a simple design, but the sound is incredibly powerful. When distorted, it has a fine texture that makes it suitable for a wide range of genres."
  • "It produces a clean tone with a good balance even when the volume is turned down. It's easy to use for practicing at home."
Negative reviews
  • "It's just so loud. It's comparable to Ecstasy, so be careful."
  • “At very low volumes, the sound can get a little muffled and lose some of its thickness.”

Friedman / RUNT 20

Product Features
  • 2 channel configuration
    Equipped with a clean channel for blues and country and a drive channel for classic rock.
  • Compact yet powerful
    By using a custom transformer, the compact 20W amplifier delivers tight low frequencies and rich midrange frequencies comparable to a 100W amplifier. The XLR output and built-in cabinet simulator allow you to capture tube tone directly.
  • Effect Loop & Master Volume
    The fully equipped loop and master volume control ensure clear sound quality even when using pedals. Low noise and distortion are less likely to occur.

The RUNT 20 is a 20W class amplifier suitable for blues and classic rock. Its all-tube circuit with two EL84 power tubes provides lightweight yet responsive distortion.

The clean channel brings out the nuances of your picking, while the drive channel produces a warm overdrive, naturally outputting everything from light distortion to moderate crunch. Featuring lively mid-highs and solid lows, this is an amp with excellent cost performance in its price range.

Positive reviews
  • "It's versatile enough to be used for everything from crunch to hard rock. The sound doesn't distort even when boosted more than you'd expect."
  • "It's only 20W, but it's loud enough. Even at high gain, it's as tight and sharp as a 100W unit."
  • "The XLR output cabinet simulation is convenient. You can get a tube-like sound even when recording at home."
Negative reviews
  • "The EQ section is common to both channels, so you can't fine-tune the sound as much as you can with the BE-50/100."
  • “It's not super high gain, so it's a little lacking for modern metal sounds.”

Friedman / Twin Sister

Product Features
  • Twin Marshall Circuit – A 45W amplifier based on a modified Marshall JTM40 circuit. Two 6L6 (5881) power tubes produce a British clean tone.
  • Dual Channels – Two completely identical channels (Gain/Master/EQ) provide a wide range of sounds from blues to rock on either channel.
  • - Equipped with an effects loop – Equipped with a series loop that allows you to naturally connect external effects while maintaining the warmth of a vacuum tube amplifier.

The Twin Sister is a 40W "twin reverb-style" amp, a rare model with two systems: a bright clean and a drive. The sound quality is high-pitched, reminiscent of the 2s JTM60, making it ideal for Strat clean tones.

The two channels can be set to the same settings without a crossover, allowing for unique uses such as playing the same sound in stereo. The low frequencies are slightly subdued and clear, making it suitable for a wide range of styles, from jazz and rockabilly to rock.

Positive reviews
  • "The clear, thick clean tone is fantastic. A must-have for twin reverb fans."
  • "Being able to use two identical channels broadens the range of sounds. Even playing in a room produces beautiful high notes."
  • "It has a classic sound, but is more reliable than the original amps. It's warm and perfect for jazz."
Negative reviews
  • "Heavy distortion isn't its intended target, so it's not suitable for metal. If you want to use heavy distortion, you'd be better off with another model."
  • "The price is a little high, and there are cheaper twin reverb options available."
Friedman

  • Single Channel
    Simple master volume and gain configuration. Hand-wired for natural response.
  • 10" combo model available
    A combo version with a 10-inch speaker is also available, providing a powerful sound that will have a strong presence even at small live shows.

The Pink Taco PT-20 is a 100W head/combo for players looking for the punchy sound of the BE-20. Its classic overdrive tone is perfect for all types of rock, covering everything from light crunch to intense high gain.

Its versatility makes it suitable for any genre of music, while its compact size and light weight make it highly portable. In particular, when combined with the custom 10-inch speaker (combo), it delivers a deep, powerful bass sound, capturing the pristine tone of an electric guitar.

Positive reviews
  • "You can enjoy BE-100-level distortion at 20W. It produces a thick sound even at low volumes, and is more than enough for a live performance."
  • "It's compact yet powerful. Even with a Strat, you can get a fat, juicy rock tone."
  • "A versatile amp with the warmth of a vacuum tube, suitable for a wide range of genres from blues to hard rock."
Negative reviews
  • "Because it's a single channel, the variety of tones is limited. It's not enough for those who want a clean channel."
  • "The head is small, but the fan noise can be a little noticeable."

Positive reviews
  • "The subtle optical compression makes the guitar sound thicker and more consistent. You can create both clean and distorted sounds just the way you want."
  • "Even when distorted, the compression effect keeps the sound from getting crushed. It sounds great when used with chorus during solos."
  • "When driven at 18V, it produces a higher-headroom clean sound and allows for greater distortion. It's versatile, depending on the settings."
Negative reviews
  • "You can do everything with one pedal, but the compression can sometimes be too strong and requires fine tuning."
  • "It's not as powerful as other standalone compressors. If you're looking for pure compression, you might be disappointed."

FRIEDMAN Summary

FRIEDMAN is a brand that brings the classic Marshall sound to a modern level. Their amps offer rich overtones and excellent response, while their effects pedals make it easy to recreate that tone.
