I used this pedal only a handful of times, and only in the studio. It works quite well and produces classic vocoder sounds with two levels of mic gain, which is great. Unfortunately, the sound wasn't exactly what I was looking for, so I didn't continue using it much. It's spent the last couple of years in a closed cabinet. I played again with it last week.. still working great, but I'm ready to let it go. Comes with the manual in the original box. Power supply not included.
