Manufacturer's ID: KTN-100MKII

The Evolution of a Modern Classic. 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.

Katana-100 MkII Main Features

  • Stage-ready 100-watt combo amp with a custom 12-inch speaker
  • Tube Logic design approach produces class-defying power, authoritative punch, and cutting presence
  • Five unique amp characters (Clean, Crunch, Lead, Brown, and Acoustic), plus newly voiced variations for each
  • Five independent effects sections (Booster, Mod, FX, Delay, and Reverb), with three selectable variations in each
  • Dedicated Pedal FX for foot-controlled wah and pedal bend
  • Updated BOSS Tone Studio software for customizing your sound with over 60 different BOSS effects, channel and global EQs, adjustable routing, and much more
  • Power Amp In for preamps, modelers, and multi-effects
  • Stereo Expand out to link with a second Katana MkII (100-watt models only)
  • Eight Tone Setting memories for storing and recalling all amp and effect settings
  • Power Control for achieving cranked-amp tone and response at low volumes
  • Three Cab Resonance options (Vintage, Modern, and Deep), selectable in BOSS Tone Studio
  • Mic’d cabinet emulation on the line, USB, and phones/recording outputs, with three Air Feel settings available in BOSS Tone Studio
  • Optional GA-FC foot controller provides complete amp control, including Tone Setting selection, effects on/off, expression pedal control, and more
  • Connections for up to two footswitches or an expression pedal
  • Effect loop, with selectable series/parallel operation and adjustable level in BOSS Tone Studio
  • Pro setups available at BOSS Tone Central

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.

Free Katana MKII Version 2.0 Software Update

Version 2.0 elevates the expressive power of your amp with newly added tone-shaping tools available in the BOSS Tone Studio app.

Contour Settings

Shape your core tone with three different Contour settings, each with four customizable frequency curves to choose from.

New Solo Block in FX Chain

Refine your lead guitar voice with a moveable Solo block, which can be assigned for on/off control via an external footswitch or the GA-FC Foot Controller.

New EQ Block in FX Chain

Moveable EQ block for additional tonal adjustment.

Two New Effects

Centa OD (Booster block), Solo EQ (Solo block)

Three Global EQs

Fine-tune the overall sound for different guitars and styles.

Expanded Cab IR Capabilities

Great amp! Top Boss quality as always.

Tony M. - 2/3/2023

I think this combo amp probably deserves 5 stars, however I have a Laney TF 200 and I have to say the Laney sounds more fat.

Antonio A. - 5/2/2023

Gerrard P. - 19/9/2022

Irmeet B. - 17/9/2022

Great solid state amp with a bit of punch when you need it, and all the amazing Katana tonal flexibility. Should have an onboard tuner though…..

William B. - 7/9/2022

Alan L. - 3/2/2022

Patrick E. - 10/11/2021

This amp is excellent! The tones and effects already contained here are smashing and super clean. Also the ability to use effects from the Boss tone studio app! Looking forward to testing this amp in a live environment with my band The Coronations!

Great amp, very uggly, but does everything you want and more for an incredible price! If you can live with the esthetics you'll get the very best, very reliable, with tones of sounds, options, and settings fora very low price. Got many expensive amps over the years, and I prefer this one.

Robert D. - 27/12/2020

Nice sound and a good range of functionality

Ian F. - 21/12/2020

Good service and a nice product that saves wear and tear on my valve amps

Jayne L. - 20/11/2020

David A. - 13/11/2020

Alan R. - 19/9/2020

Simple digital amplifier with hundreds of patches online to download. Some of these patches emulate artists and others, more importantly, model certain amp types. The amp covers most popular sounds but for me, offers a solid-state option over my two valve amps and makes for a good platform for pedals. With the effects loop I'm able to place my various delay pedals where they need to be. This is a very versatile amp and although lacking the punch of my valve amps it's great to play through and it doesn't surprise me how successful Boss are finding their Katana products.

Storr A. - 17/9/2020

Good amp, but not quite as good as I was led to believe

JACQUELINE D. - 29/7/2020

Best amp ever, not a tone it can't achieve.

william c. - 16/7/2020

Really great sounding amp. Getting to know all the features is lots of fun and the software tone studio really expands what you can get.

Chris . - 13/5/2020

Best solid state amp I've ever played, Sony use my pedals anymore!

Derek J. - 28/4/2020

Sounds superb with my Strat. Great tones and FX. Would definitely recommend this amp.
