Boss Katana KTN-HEAD Gen 3 100-watt Guitar Amplifier Head

The Next Generation of a Modern Classic

With Katana Gen 3, the acclaimed BOSS stage amplifier series evolves to take your guitar ambitions to the next level. New Tube Logic enhancements enrich the core platform with even greater sound, feel, and response, including an expressive Pushed amp character that edge-of-breakup fans will love. The BOSS Tone Studio app has also been updated, making your remote amp and effects editing workflow more intuitive than ever. Loaded with inspiring tone tools and diverse connectivity options, Katana Gen 3 is your indispensable centerpiece for studio recording, live performance, and daily practice.

The compact Katana Head Gen 3 features 100 watts of Class AB power, a unique Bloom option derived from the flagship Katana Artist Gen 3, and an onboard 5-inch speaker for practice and checking tones.


Refined Tube Logic Tones

Tube Logic recreates tube circuitry and all its complex interactions at a component level. Their 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.


"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. Along with the main external speaker output, there’s an onboard 5-inch speaker for practice convenience and dialing in sounds.


Famous BOSS Effects

Katana Gen 3 features five simultaneous effect categories loaded with essential selections from the historic BOSS library. Booster, Mod, FX, Delay, and Reverb sections offer enhanced sound quality, grab-and-go parameter controls, and three variations each for access to 15 unique effects. 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. And when the optional Bluetooth® Audio MIDI Dual Adaptor is installed, you can wirelessly edit sounds on the gig using the BTS editor app on your smartphone.


Complete Stage Command

Katana Head Gen 3 features a host of powerful tools for modern performers. Eight Tone Setting memories let you store and recall complete amp/effect setups, while rear-panel jacks support remote control with footswitches, an expression pedal, and MIDI. The GA-FC and GA-FC EX Foot Controllers extend your capabilities even further, providing complete stage control solutions for your Katana Gen 3. Switch Tone Settings, turn effects on/off, integrate multiple expression pedals, and more. The GA-FC EX model also includes an expansion option to double your footswitches or control two Katana amps at once.
