Thanks, I just ordered one!
I just had a play with the pedal and it seems to work fine, although on 2 occasions the wah just stopped and froze. When I went into the RIG page and looked at the calibrate bar, it seemed
to go down on its own, very slowly, like a capacitor draining if you know what I mean. I needed to restart the KPA before it responded again. I just had it connected without the switch btw.
I'm still on firmware 3.3 something though, will upgrade and see if that changes anything, it might be the cable I soldered...
Fingers crossed...
