The original purpose of buying the Katana 100 combo was to be a bridge until I bought my Two Rock Studio Pro 35. Before I bought the amp, I A/B'd the Katana 100 with a DRRI in-store (the DRRI at its sweet spot just below 5 on the volume and setting the Katana to emulate it), and the Katana 100 combo actually won. By simply launching the dedicated BOSS TONE STUDIO application and connecting to the. BOSS TONE STUDIO for GT-1000 (Windows/Mac) is available.
I created a few patches for the Katana using some frequency response graphs I found online. I don't claim that these are exact copies of the sounds of these amps, but they do sound pretty good to my ear. The linked file contains four patches: 1) Clean (not trying to emulate anything here, just get a basic clean tone) 2) Brownface Vibroverb 3) AB763 min (treble and bass turned all the way down on the original circuit) 4) AB763 flat (treble and bass at 12 o'clock on the original circuit) I put a graphic EQ before the pre-amp EQ, and left the pre-amp EQ flat so you can tweak the sound to taste, for room acoustics, guitars, etc. I like just a hint of breakup and saturation in my tone, so these might seem a little gainy and trebly if you don't roll back your guitar volume. On my Eastman AR371 with a P90 in the neck I roll the volume back until I hit the sweet spot for each patch, usually 8 or lower. The crunch channel seems to clean up magnificently in response to guitar volume and picking strength.
When I created these, I was using the 0.5 watt setting with the master at 50%. Feel free to adjust master and gain to your liking. I've read that as the master volume is increased, the Katana will respond like a tube amp getting its tubes pushed harder. I spent some time today trying to match my Katana to an amp based on the tweed Princeton at practice room levels.

My Princeton-ish clone has a 10' Altec and an 8' Jensen, and my Katana has a WGS 12C/S. Accounting for differences in the cabs, I think I got pretty close. The guitar I used is a laminate fully-hollow with a P90 in the neck position. The gain on the Princeton clone is around 1 o'clock with the tone control wide open.
(This clone uses a different tone stack than a real Princeton.) The tone should be rich in the midrange with a just the tiniest bit of breakup if you really hammer hard.

The amp is a little bright so you'll be turning down the treble and the presence. There appears to be a speaker break in period and the amp seems less trebly now than it did at first. By putting the Master Volume on full open and controlling the loudness with the Channel volume controlthe amp has a more reactive response more like a tube amp, some sag and bloom on the notes.
At least that's the developing mythology about the amp. As always your ear is what counts. This is from a FB group devoted to the amp, mostly shredders but the occasional jazz player.

Towards the end of last year, Boss announced the Katana series of guitar amplifiers, which we’re told owe much to their ‘Waza’ amplifier development programme. The Katanas are affordable modelling amplifiers built into MDF (rather than the more expensive plywood) cabinets — but they’ve already proven so popular that we’ve only just been able to get our hands on one to review. At the time of writing, the range comprises three combo amplifiers and one amp head: the 50W KTN50 and 100W KTN100 combos each incorporate a single custom 12-inch speaker, while the Katana 100/212 delivers 100W of power into two 12-inch speakers; and the 100W Katana-Head has no cabinet but does include a small built-in monitor speaker for practise, and can be hooked up to any speaker cabinet of the appropriate impedance. As we were going to press, the Katana Mini version was announced, and this puts some of the same technology in a smaller, more portable, battery-powered unit. In many ways the formula is quite familiar — you choose one of five amp models (Clean, Crunch, Lead, Brown and Acoustic), tweak the tone using a familiar range of drive, volume and bass/middle/treble tone controls, and then add the built-in effects. The Acoustic setting is not an acoustic emulation, but rather a setting to make the best of electroacoustic guitars. For home or recording use, you can dial in a lower power level (the minimum being 0.5W), via a rotary switch, and four user memories (two on the 50W model) are available; you press and hold the desired button to store the current settings or press briefly to recall the stored settings.
The effects section is already generously provided for, as I’ll describe in a moment, but it can be expanded using the free-to-download Boss Tone Studio editor software, which allows you to choose from 55 Boss effects. Up to three effects (one each from the Booster/Mod, Delay/FX and Reverb sections) can be used at once. You can access 15 effects from the front panel and there’s a tap tempo button in the Delay section.
An illuminated button steps through the three effects options per effect, the button’s colour changing accordingly, and turning the knob fully anti-clockwise turns the effect off. Furthermore, the Booster/Mod and Delay/FX switch to different effect types once the control knob passes the halfway point, meaning you actually get a choice of six effects types per category. Reverb delivers only reverb, but you can choose from three different reverb types.
All Katana models include footswitch and expression pedal inputs plus a speaker-emulation on the headphone output. The Katana-Head can also be controlled via MIDI. We were sent the 2x12 combo purely because it is what was available, though for studio use and the occasional pub gig I imagine the 50W model would do the job perfectly well and put less strain on both your back and your wallet. The 50W model doesn’t have the send/return loop of the larger models in the range (though it’s hard to imagine an effect that’s not already catered for!) but all models have a USB recording output, with drivers available for both Windows and macOS via the web site.
The software is very user friendly; it allows effects to be selected and edited, and the controls are closer to what you’d expect to see on a typical pedal than a studio effects processor. You can play through the amp and listen as you change or edit effects, then when you’ve loaded in your preferred choice of effects and settings, you have what amounts to an amp with a customised effects section tailored to your own needs. By way of sonic character, the Katana sounds and feels very ‘real’, and thanks to the choice of amp models it can cover all genres from clean country to nasty rock, with plenty of classic rock and blues possibilities in between. I particularly liked the Brown amp setting for more classic tones — it sounded very natural when just pushed to the edge of breaking up, and I could control that just by using the guitar’s volume knob. It’s well worth experimenting with the gain control settings too, as there’s quite a difference between running with the preamp turned up and the master down, and doing the opposite.
You can coax a very touch-responsive sound from the amp, and though I still prefer my Blues Cube for my own purposes (there’s a review of the latest model in this issue), I can’t help but be envious of the Katana’s effects section, which covers just about all requirements. I wasn’t knocked out by the somewhat wobbly sounding pitch shifter that I loaded via the software but, overall, the delays, reverbs and mod effects are all very smooth and musical. I certainly wouldn’t miss not having an effects loop on the 50W model. Overall, then, the Katana amps represent extremely good value for money and manage to provide more than enough flexibility without getting the user bogged down in complexities.
Even if you never use the editing software you won’t feel cheated — but if you decide to use it to swap one of the existing mod effects for a rotary speaker or Univibe, for example, you’ll find it very intuitive. Even the smallest amp in the range is loud enough to handle small pub gigs while being equally at home in the studio. So don’t dismiss this range because of the affordable price or the MDF cabs — they are really rather good. All contents copyright © SOS Publications Group and/or its licensors, 1985-2018.
