I just bought an Octave OC-2 on eBay, and so far it's really not what I was hoping for. If I play long notes on (say) the G string, the octave only lasts a second or two and cuts out, leaving only the higher tone. Short notes tend to work okay, though the tracking is still occasionally erratic. If I play a high double-stop, the octave jumps wildly between the two notes. Did I get a bum pedal, or is that just the nature of this beast? I've seen comments about it not having the best tracking, but I never thought it would be this dramatic. Also, the canned description eBay had for this pedal (not the part the seller typed) said it had one octave up and one octave down; the pedal I received has one and two octaves down. I know there are at least a couple versions of this pedal; does at least one of them have an octave up? I thought I remembered reading that, but I could just be crazy.
