I messed around with one today at GC, and liked it. I compared it to the Digitech Synth Wah, and I liked the SYB-3 better. It had some cool sounds I couldn't quite find on the Digitech. The Deep Impact might be a better choice, but they're scarce and pricy. Anyway, I played the SYB-3 for a while, and while I had to be pretty deliberate with my playing, it seemed to work.
