■ Easily achieve a fulfilling performance

Simply connect it to your guitar or bass, tune with the built-in tuner, select your favorite presets, and instantly enjoy high-quality sound. No need for amplifiers, effects, cables, or other equipment. And with a rechargeable battery that provides 5 hours of continuous use, you can play anywhere—in your living room, in a dressing room, or outdoors.

The premium sound of Katana
The KATANA:GO is packed with tones inherited from the acclaimed KATANA Amp series. Guitar mode offers a wide range of sounds, from BOSS's ideal high-gain Brown to the clear, crystalline Clean and fat Crunch. Bass mode offers distinctive tones, such as Vintage, which captures the rich harmonic content of a tube amp, and Modern, which is ideal for slap playing. Of course, numerous high-quality BOSS effects are also available, optimized for guitar and bass. Connect to your mobile device via Bluetooth and use the dedicated app to take full advantage of all these effects. Created sounds can be saved onboard and recalled at any time.

■Unparalleled immersion with 3D sound technology. Listening to guitar/bass sound through headphones typically feels like the speakers are right next to your ears, putting strain on the ears and making it unsuitable for long practice sessions. The KATANA:GO features STAGE FEEL, developed using BOSS's proprietary 3D sound technology. It delivers a three-dimensional, resonant sound that makes you feel like you're listening to an amp right in front of you. You can also change the stereo position of the audio played via Bluetooth, creating an immersive performance that feels like you're playing with other musicians in the studio.

■Infinite Sound Library Thirty ready-to-use preset memories are provided for each guitar and bass, allowing you to enjoy a wide variety of sounds. KATANA:GO can also load memories created with the BOSS KATANA Amp series. By accessing the online BOSS TONE EXCHANGE platform, you can download memories created by users around the world or upload your own.

■ Enjoyably and efficiently improve your skills
The KATANA:GO supports audio playback from a mobile device connected via Bluetooth. The dedicated app also features a convenient SESSION function. You can play along with YouTube content played within the app, set repeats, adjust playback speed, and even automatically switch memories at specified points. By saving your practice sessions, including settings like markers, you can recall your own personalized practice content at any time, dramatically improving your practice efficiency.

■ Expanding applications
The KATANA:GO's uses extend beyond everyday performances. Equipped with audio interface functionality, it allows you to easily record by connecting to a PC or mobile device via the USB Type-C port. In addition to the premium sound of the KATANAAmp, you can record with three-dimensional sound using the STAGE FEEL function. In addition to music production, you can also connect to a smartphone to share your performances on social media, and listen back to your recordings to hone your skills. The KATANA:GO's many uses extend beyond music production.

Wireless Control with EV-1-WL/FS-1-WL: By connecting the optional EV-1-WL Wireless MIDI Expression Pedal or FS-1-WL Wireless Footswitch via Bluetooth, you can wirelessly control functions set in the KATANA:GO app. You can use your foot to control volume/wah pedals, memory up/down, and effect on/off.
