BOSS Katana-Mini Battery-Powered Guitar Amplifier

The BOSS Katana-Mini packs the legendary Katana DNA into an ultra-compact, battery-powered amplifier that delivers rich, full guitar tone far exceeding anything else in its class. Weighing under three pounds and running on six AA batteries for up to nine hours of continuous use, the Katana-Mini is the definitive travel and practice amplifier for guitarists who refuse to compromise on tone—whether practicing at home, jamming outdoors, or playing a low-key acoustic setting where a full-size amp would be impractical.

Unlike cheap mini practice amps that use simple clipping circuits, the Katana-Mini features an authentic multi-stage analog gain circuit paired with a three-band analog tone stack (Bass, Middle, Treble) that provides real tone-shaping capability. Three amp types—Brown for thick high-gain tones with natural harmonics, Crunch for classic rock and blues overdrive, and Clean for crisp, articulate tones—cover the most essential playing scenarios. A built-in tape-style delay effect with dedicated Time and Level controls adds atmosphere and depth to any performance.

The Katana-Mini's integrated carry handle makes it genuinely portable, and its custom 4-inch speaker delivers cabinet voicing that punches well above the amp's physical size. An Aux input accepts a smartphone or music player for playing along with backing tracks, and a Phones/Recording output provides a direct signal with cabinet emulation for private practice and simple recording. The Katana-Mini runs on AC adapter or batteries, making it usable anywhere power—or the absence of it—might be a factor.
