What is Ovaltone? | "Practical Hi-Fi" refined by Japanese handmade craftsmanship

Origins and development philosophy
- Made in Japan by hand
Unlike large-scale mass production, we have a small but elite team that handles everything from design to prototyping, evaluation, and improvement. Our lineup is constantly updated with the common language of "bandwidth design that is useful in the field." - Player-driven prototyping
The company's policy is to repeatedly test the product with studio and live guitarists from the prototype stage.The product is not only designed to sound good on its own, but also to prioritize clarity and separation when mixed with a band. - The model axis is clear
FOUNTAIN = OD that leaves nuance
OD-FIVE = Modern high-gain "amp-like" style
GD type = wide range distortion
TM4086 = Fender-style sparkle
WARM/PRIME = Utility to prepare the foundation
Sound creation philosophy and circuit strengths
- Audible peaks in the midrange
The mids are raised without being too loud, the lows are tight, and the tops are left just enough. Its distinctive feature is that it stands out in the mix without hurting the ears. - Picking tracking ability
The attack is fast and the decay is natural. The curve is adjusted so that the sound reflects your playing style and dynamics without being overly compressed. - Headroom design (examination of boost and power supply operation)
Some models use internal boosting to ensure headroom. The range is wide at low gain, preventing chords from becoming muddy. Even when you step on the pedal for solos, the sound remains thick and sustained. - Affinity with the real amplifier
The low frequencies don't swell too much when boosted, the tone is set to actual values, and the S/N and gain structure are consistent in both series and parallel configurations. As a result, its strength is that it doesn't suddenly become difficult to use when combined with 4CM or external pedals. - Maintainability and individual stability
The precision of component selection and assembly ensures stable operation even in the face of temperature changes and power supply conditions, leading to praise for its high reproducibility even when touring.
