THE EVOLUTION OF A MODERN CLASSICThe Boss Katana MkII is a new and improved version of the award winning Katana guitar amp series, taking its tone and features to the next level, with more sounds, more effects, and tone shaping capabilities. With newly voiced variations available for all five amp characters, you get double the tonal options. The onboard effects categories have also been expanded from three to five, offering even more real-time processing to choose from. The usability has been enhanced too, with a power amp input for modelers and multi-FX, updated editor software, and many other improvements.

Ultimate Tone, Feel & Versatility
More Sounds, More VersatilityThe stage-class Katana MkII lineup carries from where the first generation left off, developing on the same core tones and features that have made the series such a worldwide hit. If you loved the previous 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 exceeds far beyond its price class.
5 Amp Characters, 10 Overall TonesKatana 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. The characters have now been further developed with newly voiced variations, providing a wider range of tone options to shape your personal sound.
User-Friendly Technology
Five Effects At OnceKatana MkII now features five simultaneous effects categories, putting the tone-shaping power of a huge pedalboard right inside your amp. Independent Booster, Mod, FX, Delay, and Reverb sections come loaded from the factory with three variations in each, offering 15 ready-to-play effects to select from. Connecting to BOSS Tone Studio lets you dive much deeper if you wish—customize the sections with over 60 different effect types, change the order with four different chains, and much more.
Full-Throttle SoundSupported by BOSS's Tube Logic approach, Katana MkII provides authentic output distortion characteristics heard from real tube amplifiers, with the sound and feel becoming richer and more responsive as you turn up the volume. Different to classic tube amps, 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.
Total Control
Amplify Your External GearThe Katana-50 MkII works great 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 Katana MkII's preamp and effects, letting you tap straight into the Tube Logic power section, complete with grab-and-go Power Control. When using BOSS Tone Studio, the input can be easily optimized for your particular gear with a high-pass filter and adjustable gain.
One-Touch RecallOne of the Katana-50 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 dialed in a sound with the panel controls, just save it to the desired memory with a quick button hold. Four Tone Settings (two banks of two) are available, with fast selection right from the panel. You can also connect external footswitches for hands-free control on the gig.
Ready-To-Mix Tones
USB SupportedThe Katana-50 MkII features USB and phones/recording outputs with mic'd cabinet emulation, allowing you to send mix-ready amp tones to a computer DAW or headphones.
The direct sound can be shaped with five different Air Feel settings, which are accessible from BOSS Tone Studio. Two-channel USB operation is supported, so you can track in true stereo with many of Katana's modulation, EQ, delay, and reverb effects.
BOSS Tone Studio Enhancements
Improved WorkflowBOSS Tone Studio has also evolved together with the Katana MkII amplifiers. The interface has been updated with a refreshed look, and a number of parameters have been added into the main screen for improved workflow.
There's also a dedicated Pedal FX category, making it easier to assign wah and pedal bend effects to a connected expression pedal. If you're a first-gen Katana owner, you can import your custom patches and use them all with Katana MkII.
