The original BOSS Katana was a huge hit, with its great array of tones, grab-and-go portability, incredible all-around versatility and enough power for wherever you play. The Katana MkII builds on that legacy by somehow doing more in all ways that'll help you create, record and play music.

On top of having a huge tonal range with five amp characters, the updated version offers a variant switch, which doubles the amount of voices on tap. The amount of onboard effects categories has increased from three to five, giving you more possibilities to expand your sound. There's now a power-amp input for players who use an external preamp or modeling/processor rig.

And those are just the broad strokes of the huge and numerous upgrades BOSS has made to the Katana MkII. No matter your needs, playing style or budget, the Katana MkII fits the bill.

Ten Tones on Tap
Instead of buying five different amps for five different tones, the 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. The characters have now been extended with newly voiced variations, providing a wider palette of tone options to craft your personal sound. And, if you want to further refine your tone, there are no shortage of effects to be had.

Five Simultaneous Effects, No Pedalboard
If you love the tone-shaping of effects, but want to travel easily, the updated Katana makes it easier than ever to ditch the board. 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. As BOSS is a titan in the effects world, you can connect the amp to BOSS Tone Studio, which gives you access to more than 60 swappable effects, change the order with four different chains, and much more.

Huge Sound, Low Volume
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.

Power-Amp Input to Rock Your Rig
The Katana-100 MkII 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 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 optimized for your particular gear with a high-pass filter and adjustable gain.

One-Touch Recall of Custom Setups
One of the Katana-100 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 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.

Go Wide, Go Stereo
Whether you're a wet/dry player, or you just want to rock the house with your awesome guitar tone, the Katana MkII lets you double up with ease. 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
Beyond the incredible amount of possibilities with tone, the Katana-100 MkII offers a wealth of I/O options. It features line, USB, and phones/recording outputs with miked-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.

Ultimate Control at Your Feet
The optional GA-FC foot controller is the perfect partner for the Katana-100 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’re able to recall Tone Settings, turn effects on/off, and tap in tempos. Two expression pedals can also be connected, providing foot control of volume, Pedal FX, and up to three assignable parameters (configurable in BOSS Tone Studio).

Edit Tones Like a BOSS
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.
