I downloaded the Waza Air app for iPhone and played with it a little at lunch today. I dont know if the amp models are the same, but it looks like they could be. The two environments appear to give you about the same options, apart from the 3D psychoacoustic capabilities of the Waza Air headphones, which I have never tried. It looks like the headphone software might be an update behind the Katana amps, as I counted only 20 boost pedals instead of the 22 on the Katana, which I think added a couple on the last update. I saw only the parametric EQ in the Waza Air app; maybe it doesnt have the 10-band graphic? It looks like neither system offers an extensive set of amp models to rival the selection you get from, say, a Fender Mustang. They are just good-sounding, generic, ballpark sounds instead of claiming anything really specific.
