Boss Katana GO Headphone Amplifier — Stage-Class Tone in Your Pocket

The Boss Katana GO is a personal headphone amplifier crafted for guitarists and bassists seeking authentic Katana stage tones without the burden of a full-size amp. Simply plug it into the instrument's output jack, add your headphones, and recall a memory — you won't need an amp, pedalboard, or computer interface. This model delivers premium sound for daily practice, late-night jams, and travel, with music streaming and tone editing managed via smartphone. Inside, Katana amp architecture is condensed into a 65 g body that folds down smaller than a credit card.

Stage Feel Spatial Engine and Authentic Katana Tones

What sets this model apart is the Stage Feel function, using advanced BOSS spatial technology to position amp and backing tracks in a three-dimensional sound field. Players can access presets for playing on stage or jamming with friends, customizing the experience within BOSS Tone Studio. Guitar mode offers 10 amp characters — clean, crunch, high-gain BOSS Brown, and acoustic/electric tones. Bass mode features Vintage, Modern, and Flat amp types from the Katana Bass line.

Portable Power and Battery Performance

Traveling musicians value battery life and portability as much as tone. The unit uses a built-in rechargeable lithium-ion battery for up to 5 hours of continuous playing, recharging in about 3 hours via USB-C. The integrated 1/4-inch plug rotates and folds flat, making the device a pocket-friendly 45 mm wide × 125 mm deep × 29 mm tall package at just 65 g.

• Battery Life: approximately 5 hours of continuous use per charge
• The charging process takes approximately 3 hours with USB-C, so you can get back to playing quickly.
• Weight: 65 g — lighter than most guitar picks
• Dimensions: 45 × 125 × 29 mm when folded

Tone Library, App Control, and Connectivity

Players will discover a deep tone library to explore for months. Each mode includes 30 ready-to-play memories, and BOSS Tone Studio for iOS/Android unlocks deeper editing, memory organization, and YouTube practice tools. BOSS Tone Exchange brings a community-driven library of Livesets to download and share, while Tone Setting data from Katana amps can be imported. Bluetooth offers A2DP streaming plus MIDI over Bluetooth Low Energy, and the USB-C port transforms the device into a 48 kHz / 32-bit audio interface for DAW recording or live streaming.

• Sample Rate / Bit Depth: 48 kHz, 32-bit AD/DA conversion with Roland's AF method
• Each mode supports 30 memories, so both Guitar and Bass players have quick access to favorite settings.
• Bluetooth Profiles: A2DP audio and GATT MIDI over Bluetooth Low Energy
• USB-C: audio interface function for DAW recording and social streaming

Onboard Controls and Headphone Output

Despite its size, the Katana GO offers key controls within easy reach. The top panel features Master Volume, A/B/C memory buttons, Bluetooth pairing, STAGE FEEL, and a multi-function button that doubles as a tuner. The OLED graphic display shows memory names and tuning, and the stereo 3.5 mm headphone jack delivers 30 mW + 30 mW into loads of 16 ohms or higher. For hands-free control, the optional EV-1-WL Expression Pedal and FS-1-WL Footswitch pair over Bluetooth.

• Headphone Output: 30 mW + 30 mW into 4.7 ohms output impedance
• The input impedance is 1 M ohm on the 1/4-inch folding plug for compatibility with all standard electric guitars and basses.
• Display: 128 × 32 dot graphic OLED for memory names and tuner readout
• Optional Wireless Control: EV-1-WL expression pedal and FS-1-WL footswitch over Bluetooth

Who the Boss Katana GO Is For

Boss Katana GO is ideal for players seeking silent, portable stage-grade tones. Apartment musicians, touring artists warming up backstage, parents practicing quietly, and students learning bass riffs all find value in this pocket-friendly solution. Bassists benefit from a dedicated mode with Vintage, Modern, and Flat amp types; guitarists can import Katana patches and edit them in BOSS Tone Studio. Content creators use the USB-C audio interface to record directly into a DAW or streaming app.

The Boss Katana Line and Pocket-Size Innovation

Boss has made the Katana series one of the world’s most recognized stage amp families, celebrated for Tube Logic sound and road-ready durability. Katana GO brings this technology to a new portable category, importing Tone Setting data from full-size Katana amplifiers. The optional CB-KTNGO pouch carries the device, charging cable, and earbuds for a practice system you can take anywhere.
