BOSS Katana Amplifier Series

Find your sound with the new generation of Amps for Guitar and Bass

Right now, in a practice room, basement club, pro studio, or workspace, a guitarist or bassist is powering up a Katana amp and making their mark. Across the Katana series, you’ll find the foundation of BOSS’s revolutionary Tube Logic design approach for dynamic valve tone that feels alive in your hands. Add pro-level effects to equip you for any band, gig, or setlist, plus recording capabilities that let you track, shape, and share your own productions. Katana’s name and concept are inspired by the historic samurai warriors of ancient Japan, whose traditional swords were a symbol of honor, precision, and artistry. But there has never been an amp so in tune with the modern musician.
