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.

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.

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.

Unrivaled Sound Shaping

BOSS Tone Studio for Katana Gen 3 offers new visual enhancements and graphic customization options that make crafting your tone faster and more intuitive. Explore amp and effect editing tools, change the effect order, and shape the overall sound with the three-way Contour control and multiple EQs. Dial in system-wide settings and behaviors. And organize custom setups for all your gigs. You also have access to BOSS Tone Exchange, where you can download pro setups and share sounds with the worldwide Katana community.

Save and Control Your Tones

Katana-50 Gen 3 offers several powerful tools for controlling your sounds. Four Tone Setting memories let you store complete amp/effect setups and recall them with a touch. And with footswitches and an expression pedal, you can remotely switch memories and control a variety of custom assignments that you’ve set up in BOSS Tone Studio.

Amplify External Modelers

Along with its self-contained operation, Katana-50 Gen 3 is also a great monitor for an external setup such as a direct-to-PA pedalboard. Simply connect to the Power Amp In jack to bypass the Katana preamp and use the reactive Class AB power section to amplify any modeler or external preamp.

Get Connected

Katana-50 Gen 3 includes connectivity to meet every need. Plug in headphones to practice quietly with stereo sound. And record to your favorite music software on computers and mobile devices over USB-C. All audio outputs feature IR-based cabinet sound for great direct tone, with three Air Feel types and two customizable settings in BOSS Tone Studio.
