Katana Gen 3: Inspiration Unbound
Backed by our advanced Tube Logic amplifier architecture and reactive Class AB power, the BOSS Katana series has become a standard for guitarists everywhere since its introduction in 2016. Katana amps embody decades of BOSS development knowledge, providing professional, tube-inspired sound coupled with modern advantages like onboard effects, one-touch memory recall, deep sound customization, and reduced weight. Katana Gen 3 elevates the lineup with even more range and versatility, bringing you a playing experience that goes where no other amps can.

Refined Tube Logic Tones
Tube Logic recreates tube circuitry and all its complex interactions at a component level, putting the coveted tone and feel of classic tube amp designs under your fingers. Our approach continues to evolve with refinements to the five amp characters available in previous Katana models, including the iconic high-gain Brown type. The new Pushed character spotlights internal dynamic enhancements with the pleasing touch-responsive gain of a clean combo driven into harmonic saturation. All six amp characters include a selectable variation, giving you 12 distinctive tones to support every musical style.

“Sweet Spot” Sound
at Any Volume
As every tube amp lover knows, the sound becomes richer, fuller, and more responsive as you turn up the volume. Unfortunately, it also gets way too loud for many playing situations. An external power attenuator is a common solution, but it can introduce artifacts that color the amp’s tone and feel. The integrated Power Control in Katana Gen 3 delivers the best of all worlds, letting you dial in cranked-amp inspiration with no adverse effect on the sound. Just turn the panel knob to transparently harness the level for everything from live stage playing to daily bedroom jams.

BOSS Tone Studio unlocks additional possibilities, allowing you to customize the onboard effects from 60 different types and tweak deep options not available from the amp’s panel.
