Refined Tube Logic Tones Tube Logic recreates tube circuitry and all its complex interactions at a component level. The 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 touch-responsive gain of a driven clean combo. All six amp characters also include a variation for 12 distinctive tones. Going further, the Bloom switch engages a dedicated circuit that introduces a totally different amp feel. The sound comes alive with a sharper attack and a richly dynamic low-end response, two characteristics that are difficult to achieve at once. Unrivaled Sound Shaping 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. Along with the main external speaker output, there s an onboard 5-inch speaker for practice convenience and dialing in sounds.
