The Katana for the living room
Boss launched the Katana-25 on 29 October 2026. It sits between the small Katana-Mini X and the Katana-50 Gen 3, and it is built to live at home and get played every day. Guitar World called it "the Katana that's always been missing".
The sound
The Katana series is built on Boss' Tube Logic, which is designed to make the amp respond like a tube amp when you play hard or soft. In the Katana-25, a reactive 25-watt analog power amp works with a custom 8-inch speaker. The cabinet has an open back, which gives a full low end.
The six amp types run from clean to high-gain brown sound, and each type has its own variations. One of them is voiced for acoustic-electric guitars, so you can also plug in your acoustic guitar with a pickup. MusicRadar highlighted the pushed type, which stays clean when you play softly and breaks up when you dig in.
Power Control
A switch on the top panel lets you choose between the full 25 watts and 0.5 watts. The low setting gives you the sound of an amp that is turned up, at a volume that suits an apartment in the evening. The feature comes from the stage Katana amps.
Effects and sounds
There are more than 60 effects from the Boss catalogue, and you can use up to five at once. The panel has gain, volume, bass, middle and treble, plus a tap tempo button so the delay follows the song. The tuner is built in.
Tone Setting holds 20 ready-made sounds and 10 empty slots for your own. You adjust the key settings directly on the panel, and the full range of effects is in the Boss Tone Studio app.
Bluetooth and Session
Bluetooth is built in. Stream music from your phone and play along through the speaker or in your headphones. In the app you can download sounds from other players on Boss Tone Exchange, and with the Session feature you can play along with YouTube videos and set the app to change sounds at specific points in the song.
Practice quietly and record
The headphone output doubles as a recording output. Over USB-C, the Katana-25 sends its sound straight to your computer or phone. A Boss footswitch in the jack on top changes sounds, and the wireless FS-1-WL or EV-1-WL can control it without a cable.

Questions and answers
Can I play with headphones?
Yes. The output is a stereo mini jack, so regular headphones plug straight in. With Power Control at 0.5 watts you can also play quietly without headphones.
Can I use it with an acoustic guitar?
Yes. One of the six amp types is voiced for acoustic-electric guitars, so you can plug in an acoustic guitar with a pickup directly.
Do I need the app?
No. You choose sounds and adjust the key settings directly on the amp. The app gives you access to all effects, Boss Tone Exchange and the Session feature.
How do I record with it?
Connect a USB-C cable to your computer or phone and the sound goes straight into your recording software. You can also record from the headphone output, which doubles as a recording output.
Is a footswitch included?
No, it is sold separately. The Katana-25 works with Boss FS-5U, FS-6, FS-7 and the wireless FS-1-WL, and with the expression pedals EV-30, FV-500L, FV-500H, Roland EV-5 and the wireless EV-1-WL.
