the maxon pedal works best if you don't actually play notes. Experiment with using breath pressure only.
The use of Boss OC-2 is something I picked up from Jason Ricci who turns off the effects but has the output turned all the way up, it adds a slight but noticeable edge to your sound. Try turning the octaves on that off with the pedal on.
Thanks guys! I'm glad you like it... Chris, I'll definitely give those two things a try! I'm LOVING playing through this rig. There are just so many sounds there. I'm like a kid in a candy shop!
