Very bad updates…

The app just completely stopped working after an update of some kind. Using now iOS 16.5 and aboslutely no sound comes off the app, when everything plugged like it used to be (with a classic iRig module).

Very poor support on the website regarding any compatibility chart that would help figure out what the problem might be.

Not sure what happened there…

Sucks cause the app was nice to use!

fun

I prefer this app to tonex. ( not the pedal) Ive never tried the pedal. I find to be very intuitive, and easier to find a sound that works, in spite of its fewer options. with one output going through a reamp, into a really cheap amp and a 10" speaker, I'm more then completely satisfied, best money Ive spent towards guitar tone in a long long time..
