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. Newly voiced variations are now available for all five amp characters, doubling the tonal options. And the onboard effects categories have been expanded from three to five, providing even more real-time processing to choose from. The usability has been ramped up too, with a power amp input for modelers and multi-FX, easy stereo expansion for dual amp setups, updated editor software, 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 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 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.

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—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-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.

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-100 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-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 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.

I love Sam Ash music


I absolutely love this amp. It's so versatile and it sounds amazing.



Nice but no product knowledge


Attending clerk not knowledgeable in the least.



I'd definitely recommend this


Great sound, with different watt setting. Perfect for bedroom practice or even a small venue. It can get loud if you want it.



Best Value, Excellent but Not Perfect


I'm a beginner guitar player. I had a little Behringer V Tone practice amp that I wasn't happy with, so I did some research, listened to some other amps (solid state and tube), and decided to get the Katana 100 because it fit my budget and needs. I'm very happy with the amp. The presets are great and now that I've had a chance to mess around with the settings and software I'm starting to realize I made a great decision getting this amp. I try to learn a couple new songs or riffs every week from a lot of different genres. Having the Katana allows me to mimic what the original artist had for an amp and pedals. It's more fun to practice when you can get the same tone and effects as the original. The build quality is excellent. The capabilities are almost to much. The cleans and high gain tone are really good. The ability to change wattage is awesome. .5w is a beautiful thing when you need to practice quietly. With all that being said, there are a couple things people need to understand about this amp. One it is a great Amplifier and speaker for under $400. It is not a replacement for something like a Classic Marshall, Orange, Soldano with a 4x10 cabinet. My friend, a professional guitar player, did a comparison for me and his Suhr and Soldano blew the katana out of the water for tone and volume and every other metric you could come up with other than flexibility. He also compared the acoustic side to his AER acoustic amp and again no comparison. The AER blew it away, but as he said he could buy more than 10 of the katana amps for what his AER and Soldano cost. He is also now considering buying one to gig with because he does a lot of acoustic / electric gigs and the idea of having less equipment, less weight, and something less valuable is appealing to him.



For the money it's a no brainer!


If you are looking to simplify like I was, I highly recommend this amp. I was looking at the Helix route to run in front of a couple of 112 tubes. I have own multiple Line 6 products and decided I was tired of tweaking and just wanted to start playing again. I looked at building out another pedal board and decided I really didn't want to go down that rabbit whole again. So I ended up getting two of these to run stereo and figured I would add few pedals down the road if I need to. So far I haven't needed to. I love this amps, not only for their simplicity of use but tone as well. They are not going to to replace your high end 112 tube but it's not really trying to. I can get more than acceptable substitutes for my tube amps and I added a few more great sound that I didn't already have. It really has it's own sound too and I still get the dynamics of a tube amp with the reliability and control of solid state. Win, win.



Awesome amp


Awesome powerful amp. I'm still new at learning guitar but even on 0.5 power setting just wow. Haven't had a chance yet to dive into the tone studio to explore even more options for this awesome amp. And shoutout to Dave from the Paramus NJ store A+ customer service very nice guy even walked the amp to my car. Will definitely be back, and it's worth the hour drive.



Amazing affordable amp


Its a great amplifier thats on the affordable side. I would definitely recommend it to fellow players for sure. Perfect for playing at home and not to mention the selection of preset effects it has.



Best amp for the money


This new MkII Katana sounds very professional for a non-professional price. Also good quality. You can't beat it.



Best amp by far


This amp is great value and I'd highly recommend



Knowledgeable help


Happy with the help I received from Jonathan picking this out. Knowledgeable and focused on my purchase.
