I just posted my review of the OC-2 in the reviews section, should be there soon. To back that up, here's a sound file: Boss OC-2: Direct @ 2 o'clock, Octave 1 @ 12 o'clock, Octave 2 off. I don't normally set it like this, I have the Oct 1 @ 9 o'clock, but this shows the effect off better. Cheers, PF P.S. Comments welcome and appreciated.
