OK, I know it's an older pedal that's been out for a while, but it's new to me Bought one because I thought it might be able to do double duty for me. Was hoping it could make me not miss my beloved OC-2 but be relatively easy to switch over to an envelope as well since I didn't want to have to go to a bigger pedalboard just to add my SYB-3 back onto it (yes I know it's a synth pedal, but it does have a pretty cool auto wah). So I got it tonight and have been playing with it, and my thoughts are mixed. Found a cool enough envelope filter sound on it, but was supremely disappointed to find that you can't use the Octasub setting with only the lower octave. Tonally, I think the octave below is right up there with the OC-2, but it sure is a bummer that you can't dial out the normal bass note. I downloaded the manual to see if I was doing something wrong (I wasn't), and discovered the feature that may be its saving grace...if you depress the pedal while you plug the power supply in, it turns on a cab simulator that's pretty excellent. And the cab sim has also made me feel like I can overlook its inability to dial out the main note from the sub octave, since I realized I never use the lower octave on the OC-2 by itself anyway unless I'm jamming "Sledgehammer" at soundcheck Now why they didn't just put the cab sim on a switch, I'll never know, but since I'm not a big fan of tweeter highs whatsoever, I think I can live with it. But they really should have put it on a switch. As for the synth sounds, they're kind of cool, but it doesn't have the range of the SYB-3. It has those "synth talk" sounds the SYB-3 doesn't have, but I've got no use for them. Really, I've got no use for synth sounds at all currently, but if I did, I would stick with the SYB-3. Unfortunately I don't have a gig until Monday, but I'll give it a shot. Till then, I'm giving it a mixed review. Good envelope and octave sounds and a killer cab sim, but the octave sound needs to be able to work by itself, and the cab sim should be on a switch. At least that's how I'd do it if I designed it.
