Instant Satisfaction
KATANA:GO delivers premium sound for everyday playing without the hassle of amps, pedals, and computer interfaces. Simply plug it in, connect earbuds or headphones, call up a memory, and start rocking. Onboard controls provide access to volume, memory selection, and other essential functions, and you can easily view the current memory and tuner with the built-in display. The rechargeable battery provides up to five hours of continuous playing time, and the integrated 1/4-inch plug folds down to create a pocket-size package that’s ready to travel anywhere.

Authentic Katana Tone
KATANA:GO drives your sessions with genuine sounds from the best-selling Katana stage amp series. Guitar mode features 10 unique amp characters, including clean, crunch, the high-gain BOSS Brown type, two characters optimized for acoustic/electric guitar, and more. There’s also a dedicated bass mode with Vintage, Modern, and Flat types directly ported from the Katana Bass amplifiers. Each mode includes a massive library of BOSS effects to explore, with deep sound customization available in the companion BOSS Tone Studio app for iOS and Android.

Immersive Stage Sound
The innovative Stage Feel feature in KATANA:GO provides an immersive playing experience realized with advanced BOSS spatial technology. Presets allow you to position the amp and backing music in different places in the sound field, giving the impression of playing with a backline on stage or jamming in a room with friends. It’s even possible to personalize the sound field with the intuitive tools in BOSS Tone Studio.

Limitless Inspiration
The guitar and bass modes in KATANA:GO each feature 30 memories that come loaded with ready-to-play sounds. Using BOSS Tone Studio, you can tweak the preset memories, create sounds from scratch, or import Tone Setting memories created with stage-class Katana guitar and bass amplifiers. The app also provides integrated access to BOSS Tone Exchange, where you can download professionally curated Livesets and share sounds with the global BOSS community.
