As a live performer I do not use reverb at all. I can't seem to stop reverb from getting into any of my programs. I turn off each one when the unit is unlocked and they turn back on all by themselves. Can I not just kill reverb entirely without going through all of the different types? My reverb knob is at zero, my switch is off and I try resaving, still it comes back each time. What am I doing wrong? The book tells me nothing other than bragging about all the selections. I hate reverb!!!
