Xsonic Airstep Kat Edition

The product itself works as intended. Switches through channels and effects fine and connects to your phone no problem.

Build quality is nothing special either, feels sturdy enough but also kinda flimsy at the same time.

Had major problems connecting the AirStep to the app tho. It relies on the BTS for Katana-Air app, which doesn't actually support the MK2. AirStep is supposed to make the MK2 show up as an Air to get around that, so in theory it should just work, but for me it never did no matter what I tried.

Librarian app did work, but after all the fiddling I'd already done I didn't feel like spending more money just to get it working properly.

You do get a USB-A charging cable in the box, but no power adapter, so you'll need to grab a phone charger or bring a device with a USB port to charge it.

Overall: solid hardware but the app situation is a mess and not something they tell you upfront. If you got an MK2, just know you might run into connection issues.

Honestly I'd think twice and just put that money toward real pedals that work regardless of what amp you're using, since this locks you into the Katana ecosystem pretty hard. But the upside is real, you get to switch between multiple effects without buying them separately.

Hard product to rate. Great functionality but execution is rough. Would've been a totally different story if the app just worked, being able to change settings on the fly instead of constantly disconnecting/reconnecting to a PC every time you wanna program different channels would've made this way easier to recommend.

Overall an ok product if you've got a newer Katana, might still recommend it. But honestly I feel like buying a few real pedals for the Katana and building a pedalboard over time would be more worthwhile than getting this.

As a footswitch it completely transforms the functionality of your Boss Katana. The bluetooth connectivity is so good that I have literally never used the knobs on the top other than the power attenuator and the master volume, everything else I do using my laptop or my phone. Two minor issues: first, the USB cable is a bit flimsy and only 2m long, so whilst in the bedroom or practice space this isn't a problem, I've bought a more rugged 5m long replacement from Amazon for band rehearsals and live performances. Second, the unit is just a bit ugly and cheap, and I'm not sure how long the USB connection will last. A minor issue, but worth noting. Nonetheless, more or less a mandatory expansion in my view.
