Boss Katana MK II Guitar Amplifier Head (pre-owned)

Condition: Excellent with only light signs of use.

The Katana MkII elevates the renowned Katana guitar amp series, enhancing its core platform with even more sounds, effects, and features.

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 such 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 optimised for acoustic-electric guitar. The characters have now been extended with newly voiced variations, providing a wider palette of tone options to craft your personal sound.

Five Effects at Once
Katana MkII now includes 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—customise 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 versatile Katana-Head MkII can also be used as a dedicated amplifier for a favourite preamp, modeller, 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. And with BOSS Tone Studio, the input can be easily optimised for your particular gear with a high-pass filter and adjustable gain.

One-Touch Recall of Custom Setups
One of the Katana-Head 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, simply save it to the desired memory with a quick button hold. Eight Tone Settings (two banks of four) are available, with fast selection right from the panel. And for hands-free operation on the gig, just connect external footswitches or the GA-FC foot controller.

Connect and Control
The speaker out on the Katana-Head MkII supports connection to your preferred 8-ohm or 16-ohm cabinet. And with the handy built-in monitor speaker, you’re able to check tones and practice anywhere without having to hook up a cab at all. Advanced players will appreciate the MIDI input, which provides easy integration with MIDI controllers and switching devices.

Stereo Made Easy
One Katana MkII sounds great, but playing two at once is even better. The new Stereo Expand feature makes linking two amps simple, with just one regular cable needed. You’re able to control everything from the master 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 100-watt Katana MkII models.

Ready-to-Mix Direct Tones
The Katana-Head MkII 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 foot controller is the perfect partner for the Katana-Head MkII. It connects with a single cable, requires no external power, and features a slim, rugged profile that takes up minimal space. With six footswitches, you can directly recall Tone Settings and independently turn the five effects sections on/off. The GA-FC also supports external footswitches and expression pedals, with default assignments that include tap tempo, bank selection, foot volume, and Pedal FX. A large variety of custom assignments are available via BOSS Tone Studio, including expression pedal control of up to three parameters at once.

BOSS Tone Studio Enhancements
BOSS Tone Studio has also evolved alongside the Katana MkII amplifiers. The interface has been updated with a refreshed look, and a number of parameters have been consolidated into the main screen for faster workflow. There’s also a dedicated Pedal FX category, making it easier to assign wah and pedal bend effects to a connected expression pedal. And if you’re a first-gen Katana owner, it’s possible to import your custom patches and use them all with Katana MkII.
