Enjoy legendary BOSS guitar tone wherever you play with the ultra-portable BOSS Katana-Mini. Compact, lightweight and battery powered, this versatile practice amplifier delivers impressive sound quality well beyond its size, making it perfect for home practice, rehearsals, travel and outdoor playing.

Featuring an authentic multi-stage analogue gain circuit, the Katana-Mini produces rich, responsive tones with the dynamic feel of a full-size amplifier. Choose from three versatile amp voices—Clean, Crunch and Brown—to cover everything from sparkling clean sounds and bluesy overdrive to high-gain rock and metal tones.

A genuine three-band analogue EQ provides precise tone shaping with dedicated bass, middle and treble controls, while the built-in tape-style delay adds warmth and depth, from subtle ambience to spacious echo effects.

Portable performance

Designed with portability in mind, the Katana-Mini weighs less than 3 lb (approximately 1.2 kg) and features an integrated carry handle for easy transport. It operates on six AA batteries or an optional AC adapter, allowing you to play virtually anywhere.

Jam, practise and record

An AUX input lets you connect a smartphone or music player to jam along with backing tracks, while the dedicated headphones/recording output features cabinet simulation for natural amplifier tone during silent practice or direct recording.

Whether you're practising at home, travelling or jamming on the go, the BOSS Katana-Mini delivers inspiring tone and impressive versatility in an incredibly compact amplifier.
