The Katana series has proven a huge success for Bose, gaining recognition for the cutting tones they produce. Years of expertise have been honed into the Katana range, building on the foundations set by the acclaimed Waza amplifier. The gritty, rock sound of Katana amplifiers comes from propriety circuit design and meticulous tuning. Boss have combined the best features of old and new to make Katana's the next-generation amplifiers.

The Katana KTN50 is a gig ready amplifier, with 50 watts of power and a custom 12-inch speaker producing a huge range of tones. The amp will cut through any live scenario, defining your part regardless of the accompaniment. The Katana is also ideal for home practice, providing the same distinct tones at lower volumes.

The intuitive control layout gives instant access to the whole range of the Katana's capabilities, whilst remaining inline with the sleek, modern KTN50 design. It is here where you can also access a huge range of Boss' acclaimed effects, all customisable via the free Boss Tone Studio editing software.
