BOSS introduces the new KATANA-25 (KTN-25), the latest compact 25-watt addition to its popular KATANA guitar amplifier series!

The KATANA-25 combines the dynamic sound and expressive playing feel that have made the KATANA series a favorite among guitarists worldwide in a compact design. Featuring BOSS's proprietary Tube Logic design philosophy, an 8-inch custom speaker, and a 25-watt analog power amplifier, it delivers powerful, dynamic sound.

The amplifier offers six amp types ranging from clean to high-gain tones, each with two selectable variations. It also features over 60 built-in BOSS effects, up to five of which can be used simultaneously. With the TONE SETTING feature for saving favorite sounds and a built-in tuner, the KATANA-25 is ideal for everything from daily practice to detailed tone shaping.

Bluetooth connectivity allows players to jam along with their favorite songs streamed from a smartphone. The dedicated BOSS TONE STUDIO app provides even more possibilities, including advanced tone editing, sound sharing, and the ability to play along with YouTube videos.

The KATANA-25 also features a POWER CONTROL function that switches the output between 25 watts and 0.5 watts, allowing players to enjoy powerful amp tones even at low volumes. A headphone output and USB-C port also make it convenient for both home practice and direct recording to a computer.
