The BOSS Katana-50 EX Gen 3 is a powerful upgrade to the standard Katana-50, packed with pro-level features borrowed from its larger Gen 3 siblings. This 50-watt, 1×12 combo includes a cab sim-equipped Line Out and USB out, full compatibility with BOSS’s optional GA-FC/GA-FC EX foot controllers, and an upgraded speaker. Beyond these standout specs, the amp offers six unique amplifier personalities, including Gen 3’s brand-new “Pushed” voice for dynamic edge-of-breakup tones. Hitting the Variation switch instantly unlocks alternative voicings, giving you a total of 12 tonal options.
The Boss Katana-50 EX Gen 3 also features five independent effects sections delivering a broad range of classic, stompbox-style sounds, from ambient reverbs to atmospheric delays. Add in a flexible 3-band EQ, four Tone Setting memories, a stereo headphone jack, low-wattage power control, and BOSS’s updated Gen 3 Tone Studio app, and you’ve got a versatile combo built for both practice and performance.
At the heart of the Katana Gen 3 series is an evolved version of BOSS’s renowned Tube Logic technology, designed to capture the feel and harmonic complexity of real tube amps. These refinements push every Katana model to new levels of valve-inspired realism, most notably in the new Pushed amp type.
The Pushed voice recreates the coveted edge-of-breakup sound, embodying the touch sensitivity and organic dynamics of a tube combo turned up to the brink. Gen 3 also introduces upgrades to the Tone Studio software, with UI and workflow improvements that make dialing in your tone more intuitive than ever.
Alongside the new Pushed option, the Katana-50 EX Gen 3 retains all five MkII voices—Lead, Crunch, Brown, Clean, and Acoustic—each further enhanced by the updated Tube Logic. Dirt tones range from gritty overdrive to searing ’80s-style rock, while the Clean and Acoustic modes provide shimmering clarity. Combined with the Variation function, you have 12 distinct amp tones at your command.
The amp’s Power Control lets you achieve cranked-amp tone at manageable volumes, and silent operation is possible by routing the Line Out, USB, or headphone outputs with cab simulation enabled—perfect for both stage and studio.
If you’ve got a favorite floor unit or preamp, the Katana-50 EX Gen 3 includes a dedicated power amp input. This allows you to bypass the preamp section entirely and tap directly into the 50-watt Class AB power amp, delivering pure, transparent power to your rig.
