The Katana-50 MkII EX expands on the capabilities of the popular Katana-50 MkII model, providing more performance versatility in the same portable design. GA-FC and GA-FC EX support allows you to select Tone Setting memories, turn effects on/off, and more with a dedicated foot controllers. There’s also a line output for sending mix-ready tone to a house PA, plus the ability to link a second Katana MkII amp with the Stereo Expand feature.

Katana MkII takes the acclaimed Katana guitar amp series to the next level, turbocharging the core platform with more sounds, more effects, and more features. Cover any style with five amp characters and five variations. Colour your tones with a wide variety of customizable BOSS effects. And extend your range with the latest BOSS Tone Studio software, a power amp input for modelers and multi-FX, and many other enhancements.

The stage-class Katana MkII lineup picks up where the first generation left off, building on the same core tones and features that have made the series a worldwide smash. If you loved the original Katana amps, you’ll love Katana MkII even more. And if you’re new to the party, get ready for sound, feel, and versatility that soars far beyond its price class. Katana MkII’s five primary amp characters offer everything from organic vintage tones to modern high-gain sounds, plus a dedicated voice optimised for acoustic-electric guitar. Each character also includes a selectable variation, providing a broad palette of tone options to craft your personal sound.

All Katana MkII models feature five simultaneous effects categories, putting the tone-shaping power of a massive pedalboard right inside your amp. Independent Booster, Mod, FX, Delay, and Reverb sections come loaded from the factory with three variations in each, providing 15 ready-to-play effects to choose from. Connecting to BOSS Tone Studio lets you dive much deeper if you want—customize the sections with over 60 different effect types, change the order with four different chains, and much more.

Backed by BOSS’s Tube Logic approach, Katana MkII delivers the authentic output distortion characteristics of genuine tube amplifiers, with the sound and feel becoming richer and more responsive as you turn up the volume. But unlike that classic tube amp, Katana MkII’s variable Power Control makes it easy to fly in the sweet spot without getting fired from the gig or kicked out of the house. Just throttle back the overall volume as needed to enjoy inspiring, cranked-amp sound anywhere you play, from bedroom to stage.

The Katana-50 MkII EX rocks as a standalone amp, but it also excels as a powered cabinet for a favourite preamp, modeler, or multi-effects unit. Connecting to the rear-panel Power Amp In jack bypasses the onboard preamp and effects, letting you tap straight into the Tube Logic power section, complete with grab-and-go Power Control. And with BOSS Tone Studio, the input can be easily optimised for your particular gear with a high-pass filter and adjustable gain.

One of the Katana MkII’s most powerful features is the ability to store favourite amp character and effects setups in Tone Setting memories for instant recall. After you’ve dialled in a sound with the controls, simply save it to the desired memory with a quick button hold. Four Tone Settings are available for fast selection from the panel or optional FS-series footswitches. The GA-FC and GA-FC EX offer expanded foot control, giving you access to eight Tone Setting memories (four panel settings plus four configurable in BOSS Tone Studio), individual effects on/off, and more.
