The Boss KTN-50 is a brand new guitar combo amp following on from the development process behind the now iconic Waza amplifiers. The idea here is to effectively have a world class Boss multi-effects unit, fully integrated into an amplifier in ways like never before. Complete USB connectivity and access to Boss's Tone Studio editing software allows for up to 15 effects to be stored within this amp at any one time.
Katana, the traditional sword carried by the historic samurai of Japan is a symbol of honor, precision, and artistry in Japanese culture. Adopting the majestic sword’s name with pride, the Katana amps deliver smooth, cutting rock tones honed by generations of BOSS dedication and expertise. Featuring proprietary circuit designs and meticulous tuning, the Katana series combines traditional craftsmanship and breakthrough functions to produce true next-generation rock amplifiers.
Each Katana amp features five selectable amp characters: Clean, Crunch, Lead, Brown, and Acoustic. Every character was fine-tuned by the BOSS engineering team to offer rock players a wide range of professional sounds. Deriving its essence from the Waza amp, the Brown character delivers refined high-gain tone sought after by the world’s greatest rock players. The Acoustic character further enhances the Katana’s versatility, providing natural tone for acoustic-electric guitars.
Each Katana amp also includes integrated access to 55 BOSS effects, which are customizable using the free BOSS Tone Studio editor software. Users can load 15 different effects in the amp at one time, and use up to three effects at once.
With the powerful Tone Settings feature in the Katana amps, players can store amp and effects settings to recall perfectly tweaked setups instantly. It’s also possible to connect optional footswitches and expression pedals for hands-free control. The Katana-Head supports control via MIDI as well.
While the Katana amps include many advanced features, they offer intuitive interfaces that allow players to dial in sounds quickly. An innovative Power Control function lets
