New Sounds and Stereo Linking Come to the BOSS Katana-100 MkII

The BOSS Katana-100 MkII is the latest installation in BOSS's esteemed line of Katana series amplifiers. And whether you're interested in accessing its pummeling 100-watt output section and platform-perfect 12-inch speaker to amplify your existing modelers and preamps, or in building your dream tones from the ground up to create the ultimate all-in-one gig and practice solution, take it from Sweetwater — the BOSS Katana-100 MkII is a powerful tool in the hands of any electric or acoustic player. Cab-emulated outputs and monitoring make the BOSS Katana-100 MkII a truly silent stage and studio guitar solution, while multichannel footswitch support provides hands-free remote access to every sound in your arsenal. New amp variations and access to 60 timeless BOSS effects within the BOSS Tone Studio editor make the 100 MkII a tone tweaker's holiday. There's even single-cable stereo operation for running dual Katanas from the stage — the perfect way to fill space in a single-guitar outfit.

The BOSS Katana MkII series

With five distinct amp characters to choose from, support for acoustic-electric guitars, and access to a wide range of customizable effects, the BOSS Katana MkII series represents a new generation of flexible amplifiers for practice and performance. Familiar controls allow for fast tone shaping, and you can use the BOSS Tone Studio editor software to further customize your amp settings and effects. The BOSS Katana-100 MkII is also equipped with an adjustable Power Control that allows you to achieve cranked-amp tone at lower volume levels. For a does-it-all amplifier for electric and acoustic-electric guitar, you definitely need to check out the BOSS Katana-100 MkII combo amp from Sweetwater.

What's new in the BOSS Katana-100 MkII

Here's a quick list of the hottest features in your second-gen BOSS Katana-100 combo amplifier:

  • 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'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 Expand — You can fill every side of a stage with breathtaking stereo effects using the Katana's built-in Stereo Expand link. Simple primary/secondary 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.
  • New amp models — The classics you love are back in full effect in the Katana MkII. Only now, you can access new variations on the original five amp models to create an even more versatile gigging platform, from country cleans to metal gains to acoustic-voiced amplification.
  • Updated BOSS Tone Studio — Customizing your sound within the Katana MkII is easier than ever using the new and improved BOSS Tone Studio software; 60 BOSS effects, channel-by-channel EQs, adjustable routing, and much more await your every command.

Ready for any style of music, even acoustic-electric

The BOSS Katana-100 MkII packs five distinct amp voicings. Clean, Crunch, and Lead cover the range 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. No matter what style of music you play or even what kind of guitar you play, there's a world of tone to explore in the BOSS Katana-100 MkII combo amplifier.

Cab-emulated outputs for silent recording and performance

While the BOSS Katana-100 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 BOSS Katana-100 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.

Powered by the NEW BOSS Tone Studio

The BOSS Katana-100 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 each effects type, with a color-coded button to switch between preset effects. To completely customize your effects and amp settings, connect the BOSS Katana-100 MkII to your computer via USB and load up the Tone Studio software. Create your own setup, or download setups created by pro guitarists at the BOSS Tone Studio website. Best of all, the BOSS Katana-100 MkII can store multiple custom amp and effects profiles for instant recall, making this combo a versatile multichannel amplifier.

BOSS Katana-100 MkII Combo Guitar Amplifier Features:

  • Versatile combo amp with 5 amp voicings, customizable effects, and editor software
  • Amp characters include Clean, Crunch, Lead, Brown (derived from the BOSS Waza amp), and Acoustic (for acoustic-electric guitar)
  • 60 timeless BOSS effects, accessible from the BOSS Tone Studio
  • Variable Power Control allows you to achieve cranked-amp tone at lower volume levels
  • Shape your tone quickly with dedicated Gain, EQ, and Effects controls

Long time tube snob completely blown away!!

I can't say enough about the mark II Katana, I own two and run them in stereo with a GA-FC foot switch. The core tones are great, and easy to use, but using Boss tone studio and dialing in some additional parametric EQ, assigning effects, and using the foot switch, I have everything I need for studio recording, and live playing!! This amp has been a godsend for a guy like me who's never wanted to tweak endlessly with modeling solutions. Plus, with the class AB power section, she's a real amp!!!
Music background: Professional gigging musician

Just A Ton Of Fun!

I've been trying a lot of modeling amps lately and this one is getting alot of attention. If I had infinite resources when I started playing guitar in the 80's, I would have bought most of the pedals represented in this amp. I am now playing out my youthful rockstar fantasies with all of those sounds I wanted to hear eminating from my amplifier back then. Funnily enough, my favorite thing about this box is the 0.5W setting. I'm not that kid back in the 80's cranking the volume up after school. I'm now a mature adult with a respect for the people around me and this setting gives me the ability to get that cranked up sound without the insane volume. If you're touring and playing arenas, you're not going to be using this amp on stage. But if you're practicing backstage or in your bedroom at home, this effects filled combo should be everything you need.

FINALLY, an amp for my archtop

I've been test-driving and agonizing over which Amp to buy for my hand-carved jazz archtop guitar for the past 3 years. The bass response from my guitar just blatted out every amp I've tried. Just this past year, I realized that what I needed was an acoustic amp, because that in fact is why my guitar is, albeit with a floating humbucker. I went online and watched videos of people playing various amplified acoustic guitars and came across the Boss Katana 100. It replicated acoustic tones beautifully and was 1/3 the price of the Schertler I had my eye on. I was put off a bit by all of the videos which showcased the metal crunch voicings and distortion variations on the Katana amps, as I was after a pure clean sound with a hint of reverb.
Today, my Katana arrived and I immediately plugged in and switched on the amp acoustic channel. Without much trouble I dialed in the sound I wanted on the panel and it is perfect!
So here's a shout out to all the carved archtop players out there looking for that amp that treats your guitar well. I don't need all the bells and whistles that this amp offers, but it is well worth its weight in pure jazz tone!

Great Amp!

Besides TJ and Greg being so helpful with my purchase, this amp is great!!! I am having so much fun going through all the tones and effects and it is so simple. I wish I had bought one sooner
Music background: Have played many different instruments throughout the years. Primarily guitar and bass for the last 40 years. Build my own instruments and try to teach when ever I can.

Great amp once you figure it out.

I've had this amp for over a year. I'm a rhythm player in a cover band that plays classic rock. It was okay out of the box, but once I started playing with the software (pedals, equalizer, compression, reverb, delay, etc.) it got mind blowing. The equalizer is the most important part. Once I got it eq'd for my SG it was heavenly. I recommend YouTube. Especially Studio Rats. I gig with it about six times a month and it is reliable and weighs almost nothing. I also recommend the foot switch. I'm going to buy another one in a couple of months to have at home because mine stays on the band trailer at the drummers house. I can't say enough good things about this amp or Sweetwater.
Music background: 25 years playing and recording.
