Experience the Evolution of a Modern Classic - The Boss Katana-50 MkII EX 50-Watt Guitar Combo Amplifier

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 our 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. Color 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.

More Sounds, More Versatility

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.

Five Amp Characters, Ten Overall Tones

Katana MkII's five primary amp characters offer everything from organic vintage tones to modern high-gain sounds, plus a dedicated voice optimized for acoustic-electric guitar. Each character also includes a selectable variation, providing a broad palette of tone options to craft your personal sound.

Five Effects at Once

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.

Full-Throttle Sound Every Time You Plug In

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.

Amplify Your External Gear

The Katana-50 MkII EX rocks as a standalone amp, but it also excels as a powered cabinet for a favorite 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 optimized for your particular gear with a high-pass filter and adjustable gain.

One-Touch Recall of Custom Setups 

One of the Katana MkII's most powerful features is the ability to store favorite amp character and effects setups in Tone Setting memories for instant recall. After you've dialed 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.

Stereo Made Easy

One Katana MkII sounds great - but playing two at once is even better. The Stereo Expand feature makes linking two amps simple, with just one regular cable needed. You can control everything from the main Katana MkII, with stereo-compatible effects like chorus, delay, reverb, and others distributed across both amps for a wide, immersive sound field. Stereo Expand is supported on all Katana MkII models except the Katana-50 MkII.

Ready-to-Mix Direct Tones

The Katana-50 MkII EX features line, USB, and phones/recording outputs with mic’d cabinet emulation, letting you send mix-ready amp tones to a PA system, computer DAW, or headphones. The direct sound can be shaped with three different Air Feel settings, which are accessible from BOSS Tone Studio. Two-channel USB operation is supported, allowing you to track in true stereo with many of Katana's modulation, EQ, delay, and reverb effects.

Compact Gig Commander

The optional GA-FC and GA-FC EX foot controllers are the perfect partners for the Katana-50 MkII EX. They connect with a single cable, require no external power, and take up minimal space. With six footswitches, you can directly recall Tone Settings and independently turn the five effects sections on/off. They also support external footswitches and expression pedals, with customization via BOSS Tone Studio. The GA-FC offers standard control, while the expanded GA-FC EX provides the ability to control two amps together, connect another unit for additional foot control, and more.

Go Deeper with BOSS Tone Studio

BOSS Tone Studio takes the Katana MkII experience even further, allowing you to customize the amp for your style and touch. Change up the factory-loaded effects, adjust effect order, shape the overall tone with global EQs, tweak the cab resonance, and much more. And with Livesets, you can save favorite setups and instantly reconfigure your Katana MkII for different playing situations.
