BOSS's Flagship Katana Amp Just Got Better

BOSS ups the ante with the latest release to its flagship Katana Artist amp. The Artist MkII puts more tones, more features, and more tone-shaping potential right at your fingertips. Katana's five Tube Logic amp models now include an alternate voicing each (accessible via the Variation switch), for a total of 10 core tones available directly from the front panel. And with five simultaneous effects onboard to diversify your sounds, a 3-way mid Contour for smoothing out vintage voicings, and an adjustable Solo boost all within stage reach, the BOSS Katana Artist MkII supplies an even more classic-amp-like playing experience. Despite its simplicity, inside this streamlined combo are the bones of some of the most sophisticated amp rigs on the planet, including MIDI footswitch support and a stereo link to envelop both sides of the stage in lush 3D reverbs, delays, and more. The Artist MkII's Class AB power section delivers 100 watts of that tube amp push and pull. And a custom-voiced WAZA 12-inch speaker delivers the punch, richness, and harmonics of a British green-backed speaker stack, all with the convenience of a highly giggable 12-inch combo.

10 amp tones plus mid Contour

The BOSS Katana Artist MkII packs five distinct amp voicings, optimized for the best possible sound with the updated cabinet and custom speaker. Clean, Crunch, and Lead cover the gamut from chiming clean tones and gritty rhythm tones to solo-worthy high-gain leads. As an added bonus, the Brown setting is derived from the BOSS Waza amplifier — think iconic '80s metal. And finally, the Acoustic mode allows you to plug in your acoustic-electric guitar too. What's really handy in the Artist MkII is that each amp gives you an alternate voicing with a press of the Variation switch, creating a total of 10 core tones for you to sculpt your sound. And with a 3-way Contour switch to tame or enhance your midrange, there's no end to the tonal variations you can explore directly from the Artist MkII's front panel.

Three custom EQ curves

Our favorite amps are marked by their distinctive tone stacks. The Katana Artist MkII allows you to sculpt the response of your Bass, Middle, and Treble controls within the Tone Studio editor to best suit your amp and guitar choice.

Variable Solo boost

Moving from rhythms to lead work usually requires an output boost to achieve parity levels. Traditionally, this has been accomplished with clean boosts, overdrives, volume pedals, and our personal favorite — the 10-foot long jump to reach the amp's master volume at the last possible second. The BOSS Katana Artist MkII gives you a footswitchable Solo boost with adjustable output to boost your level to center stage and return you to sensible rhythm levels.

10 core tones, 3 custom EQ curves, a 3-way Contour toggle, and a fully adjustable Solo boost await you in the BOSS Katana Artist MkII.
The BOSS Katana Artist MkII gives you impressive I/O — including cab-emulated headphone/USB outputs and stereo linking — to match its class-leading tones.

Cab-emulated outputs for silent recording and performance

While the Katana Artist MkII offers a Power Control for getting cranked-amp tone at a low volume level, you can achieve truly silent operation onstage or in the studio by connecting the amp's line output to a line input on your recording device or a PA, completely bypassing the speaker. Cab emulation is available on the USB and headphone outputs, as well, so however you choose to monitor your Artist MkII, it'll feel like you're standing in front of an amp. Selectable cab resonance (Vintage/Modern/Deep) and Air Feel miking emulation (direct, distant, or blended) allow you to tailor emulated tones to taste.

Power Amp In(put)

Got a floor unit or tube preamp you can't live without? You can access all 100 watts of the Katana Artist MkII's Class AB power section using the MkII's power amp input. Here you bypass everything before the power amp and speakers, so what you hear is exactly what you expect — only live and in living color.

Stereo expandability

You can fill every side of a stage with breathtaking stereo effects using the Katana Artist MkII's built-in Stereo Expand link. Simple master/slave operation by way of a single guitar cable makes setup a breeze. In this mode, you can access choruses that envelop the listener in a swath of oceany motion, delays that ping-pong from ear to ear, and reverbs that descend like a cloud upon a room.

Powered by the BOSS Tone Studio editor

The Katana Artist MkII supports 60 timeless BOSS effects, and you can load an entire series of them for instant access. The amp's Booster/Mod, FX/Delay, and Reverb controls give you easy one-knob access to up to five simultaneous effects type, with a color-coded button to switch between preset effects. To completely customize your effects and amp settings, connect the Artist MkII to your computer via USB and load up the Tone Studio software. Here you can create your own setup, or download setups created by pro guitarists at the BOSS Tone Studio website. Best of all, the Katana Artist MkII can store multiple custom amp and effects profiles for instant recall, making this combo a versatile multichannel amplifier.

12-inch "green" speaker excels in tone and handling

The green backing on the Artist MkII's stock speaker communicates more than just color. The WAZA G12W's unmistakable throatiness and presence — a sound which Eddie identified as "brown" — are inspired by a consummate 25-watt British speaker of the 1960s. But unlike the original, this green meanie is engineered to weather all 100 watts of your Artist MkII's power section, without unwanted breakup or limiting. This means whether you're chunking out clean chords or dropping progressive metal powerbombs, the WAZA G12W is able to dish out every ounce of tone your Katana can throw at it.

"Effectively, it's a remodeled vintage Greenback: higher powered, better magnet, new paper cone. We've redesigned the speaker for the best possible sound."Matt Knight of BOSS on the Katana Artist MkII's WAZA Craft G12W Guitar Speaker

4) KATANA Artist says what?

Two Stereo Air Moving Machines. 2) KATANA's stereo espand mode. Bottom 2) KATANA'S amp input for GT-1000 core in Stereo. Last two pictures are KATANA risers I made that have iso spikes to peirce padded carpet floor so the stack sits soild and then there are iso spikes between the stacked cabinets so the KATANA sound is isolated from the GT-1000 core sound, but the real reason is BOSS screwed up on the rubber feet height and placement. The rubber feet doesn't clear the strap handle so the stack is unsteady and the placement interfers with the amp mount screws so the new 1" rubber feet I installed still didn't solve the problem. 1 1/8" iso spike pads to the rescue and also decouples the cabinets from each other. BOSS if you read this correct this issues so others can stack their Artist if so desired. Maybe that's why they came out with the new Artist Head and 212 cabinets. LOL

Checks Every Box

The Artist Speaker is what sold me..One of the best 12" I have ever heard. The speaker alone is half the cost of the Amp..Out of the box, it is a clean canvas ready for any pedal. The built in chorus, delay and reverb are phenomenal. Patches downloaded from Librarian are impressive, and Global EQ works well. You can practice at home, record, practice with a band, and gig at a club with this amp. It's a complete no brainer for the price! Even if it only lasts me 3 years, I'm getting another one from Sweetwater!

Finally, a solution for working musicians with some common sense....

This is a great little amp. Plenty of juice if you want to run through a set of 4x12 cabs, but you don't need to. This thing is plenty loud on its own. Sounds great for what you pay, and you can setup multiple tones and save them to be brought up via the additional footswitch. Makes my gig rig much more simple, and no fussy tubes to worry about. I have other working musician friends that are tube snobs, and won't play anything else live. I have had multiple compliments on my tone at shows, but my amp is hidden, so nobody knows what i'm playing through. They are shocked to find out its a solid state 500 dollar amp. I'm performing, not in a studio recording, so for me solid state is fine. Its reliable and versatile. I keep my tube amps at home now for the most part. I still love them, but we do a lot of festivals where we have minimal setup time between acts, and I need my rig ready to go quickly. Great job Boss!

Just Wow!

I had to open my mind about solid state amps.
I own Friedman, Marshall,Vox, Fender, Ampeg,
Tube Amps but wanted to give these Katana's a go.

First off, The dynamic playing feel is very good thanks to the tube logic technology in this amp and if you read about it in depth this is not a modeling amp at all.

These amps can be bright or dark and mellow. the key is to dial it in same as any anp. If you don't want bright and brittle blah blah, dial it out.

Like metal? nails it. Like Jazz? nails it. this does it all.
Ive been doing a 'Steely Dan' type project lately and Wow! it's there. I'm using two of these in stereo with my pedal board running thru the FX loop so I can mix my analog pedalboard FX with the Katana's Fx. = almost limitless possibilities via 8 channel presets = banks A+B controlled via the GA-FC foot switch or additional dedicated foot switches and expression pedals as I'm doing.

You can run your pedal board into the Power Amp in jack as well as in front. sounds great once you dial it in like any amp.

I haven't tried the dual link feature yet. The Boss tone studio is easy to figure out just by looking at it and really gives you serious tweak ability that isn't menu diving. It's straight forward, simple and powerful

The sound of these with the waza greenback speaker is rich and full. It can be punchy in your face or subdued mellow and warm and anything in between depending on what kind of equipment you have same as any amp

I'm very happy with my purchase of these amps and I've barely scratched the surface of what they can do.
Once you dial your sound in it's plug and play serious professional gigging tone.

I hope this helps. See the pic of my Katana rig.

Best Amp finally

Finaly found the perfect Amp for home with versatility and simplicity to function. It's a ton of fun to have access to all the Boss pedals, and EQs which when minimally adjusted make a difference in your tone. The Waza speaker was worth the up grade to me though I still have the 2 x 12 100 watt that I run in stereo, which I highly recommend. Can't imagine playing any other way. Sound comes from all directions. Downloading patching and tweaking is great too, but opening up tones studio and making if your own is the best. Thanks Mark Magdich for all your continued support and guidance with equipment.
