Hardly used! Octave is just not essential in my current gig. Octaves -1 and -2 (similar to OC-2 "but better" per reviews). Works off 9v or 12v. Very synthy! http://m.youtube.com/watch?v=wFlkSlIZD_M
Trade bait for (in order of pref):
-Markbass Chorus / Flanger
-MXR Bass Chorus
-Markbass Super Synth
Throw what you've got at me, the worst I can say is no.
These are $159 on the Bay. If buying, asking $110 shipped.
