I'm searching for just a simple octave up pedal. Nothing fancy, just one octave up. I'll build the thing myself if I have too. The EH Micro Pog is expensive, the Boss OC-3 funny sounding and expensive, and pretty much everything else has a fuzz or comes inside a another pedal (Whammy, PS-3, etc.). The little I know about octave-up comes from schematics from an octave up fuzz. I know it involves diodes and a transformer. Other than that, I haven't a clue.
