Will do, Perry. After some more fiddling tonight, I was able to reproduce a few more eccentricities, all related to Pitch Glide. Two amp models, Hi Gain Green and Insane Red, won't respond at all to the pitch glide adjustment with the FX knob. Also, when I use the FBV toe switch, it toggles between volume and pitch glide instead of wah for those two models. I can't get pedal wah to work with them at all. I've tried rolling back to 1.04 firmware and reinstalling 1.52 with no luck. I'll bring it to my local store to see what they can do.
