Take your guitar tone to the next level with the BOSS Katana-50 Gen 3, the latest evolution of the acclaimed Katana amplifier series. Combining advanced Tube Logic technology, powerful onboard effects and flexible connectivity, this 50 W combo amp is equally at home on stage, in the studio or during everyday practice.

Powered by a responsive Class AB amplifier and a custom 12-inch speaker, the Katana-50 Gen 3 delivers authentic tube-inspired sound with exceptional dynamics and feel. The new Pushed amp character recreates the expressive response of a clean valve amp driven into natural saturation, while five additional amp voices and selectable variations provide a total of 12 distinct tones to suit virtually any playing style.

Professional sound at any volume

Integrated Power Control lets you enjoy the rich tone and responsiveness of a fully driven amplifier without excessive volume, making it ideal for everything from bedroom practice to live performances.

Built-in BOSS effects

Five independent effect sections—Booster, Mod, FX, Delay and Reverb—provide access to high-quality BOSS effects directly from the amp. Each section includes three selectable variations, while the BOSS Tone Studio software unlocks over 60 effects, deeper editing options and complete signal chain customisation.

Customise and save your sound

Store your favourite setups using four Tone Setting memories for instant recall. The updated BOSS Tone Studio software makes creating, editing and organising patches easier than ever, while BOSS Tone Exchange allows you to download and share presets with players around the world.

Designed for performance and recording

The Katana-50 Gen 3 includes comprehensive connectivity for modern musicians. Record directly to a computer or compatible mobile device via USB-C, practise silently with headphones using cabinet simulation, or connect an external modeller through the dedicated Power Amp In for use as a powered monitor.
