Tube Logic Amplification Delivers Expressive Katana Tone

At the heart of the Katana-25 is BOSS's acclaimed Tube Logic design philosophy, which recreates the dynamic response, tonal richness and playing feel of a traditional tube amplifier through a reactive 25W analog power section. Paired with a custom 8" speaker and optimized open-back cabinet, this design produces full, articulate sound with punchy lows, detailed highs and a natural response to picking dynamics. Six amp characters with additional variations cover a broad tonal spectrum, from pristine cleans and warm crunch to powerful high-gain sounds, including a dedicated setting for acoustic-electric guitars. Selectable Power Control switches between the full 25W output and a 0.5W mode, allowing players to explore saturated amplifier tones at more manageable home volumes without sacrificing the expressive character of the Katana sound.

Over 60 BOSS Effects Expand Your Creative Range

The Katana-25 puts an extensive collection of BOSS effects at your fingertips, with more than 60 available effects and the ability to use up to five simultaneously. From overdrive and distortion to modulation, delay and reverb, these effects provide a wide range of creative options without requiring a separate pedalboard. The intuitive Tone Setting section includes 20 ready-to-play factory presets and 10 additional memory slots for saving personalized sounds, making it easy to explore different amp and effects combinations. Dedicated Gain, Volume and three-band EQ controls provide familiar hands-on sound shaping, while a tap tempo button simplifies delay adjustments and an onboard tuner keeps your guitar ready to play. For deeper customization, the companion app provides access to detailed amp and effects parameters, allowing players to refine their favorite sounds and save them for quick recall.

Bluetooth Connectivity and USB Recording Enhance Home Practice

Built-in Bluetooth transforms the Katana-25 into a versatile practice companion, allowing you to stream songs wirelessly from a smartphone or tablet and play along through the amplifier. The dedicated companion app expands the experience with detailed sound editing, access to shared tones through BOSS Tone Exchange and an integrated Session function for practicing alongside YouTube songs and video lessons. Players can even configure automatic Tone Setting changes during video playback, making it easier to follow arrangements that call for different sounds. A dedicated headphone output supports quiet practice, while the class-compliant USB-C audio interface provides a convenient connection for recording directly to a computer or compatible mobile device. Optional footswitch and wireless control accessories offer additional flexibility, making the Katana-25 equally useful for focused practice, exploring new techniques and capturing musical ideas at home.
