Boss KTN-25 Katana Gen 25W Combo Guitar Amplifier

Your Tone, Dialed In at Home
The BOSS Katana-25 brings the acclaimed Katana sound to a compact 25-watt combo built for everyday practice. BOSS Tube Logic gives it the warm, dynamic feel of a tube amp, and a custom 8-inch speaker in a sturdy, lightweight cabinet delivers full, punchy sound. With six amp characters, over 60 BOSS effects, built-in Bluetooth, and the BOSS Tone Studio app, it's an easy way to find your sound, learn new songs, and record your ideas.

Ready to Rock
The Katana-25 comes loaded with great-sounding preset tones, so you can plug in and start playing right away.

Genuine Tube Amp Tone and Feel
BOSS Tube Logic makes the power section and speaker respond like a tube amp, with warm lows, clear highs, and punchy dynamics.

Solid Cabinet, Lightweight Design
An open-back cabinet and custom 8-inch speaker deliver big sound from a compact amp that's easy to move around.

Premium Sounds for Every Style
Six amp characters cover everything from clean to high gain, including one voiced for acoustic-electric guitars, and you can run up to five effects at once.

Inspiration at Your Fingertips
Choose from 20 preset tones plus 10 open memory slots, tweak sounds right from the panel, set delay time with tap tempo, and tune up with the built-in tuner.

Selectable Power Control
Switch between the full 25 watts and a 0.5-watt setting for quieter practice.

Jam and Learn with Onboard Bluetooth
Stream music from your phone to play along, edit tones wirelessly in the BOSS Tone Studio app, and use the Session feature to play along with YouTube videos as the amp changes tones automatically.

Remote Operation
Change tones hands-free with a footswitch, or go wireless with the BOSS FS-1-WL footswitch or EV-1-WL expression pedal.
