About this product
Overview & specifications
The BOSS Katana-25 is a compact 25-watt guitar combo with an 8-inch speaker, six amp characters and built-in Bluetooth. Designed for home playing, it combines hands-on controls with onboard effects, headphone practice and USB-C recording.
Explore clean, driven and high-gain sounds, or select the character designed for acoustic-electric guitars. Over 60 BOSS effects are available through BOSS Tone Studio, with up to five running together. The amp provides 30 memories: 20 supplied presets and 10 empty slots for your own setups.
Use the gain, volume and three-band EQ controls to shape your sound, then switch from full power to 0.5 watts for lower-volume practice. A built-in tuner and delay tap tempo keep everyday adjustments close at hand.
Stream backing tracks over Bluetooth, practise through headphones, or record directly to a computer or mobile device using the class-compliant USB-C interface. BOSS Tone Studio adds detailed editing, Tone Exchange access and a Session function for playing along with YouTube videos.
