I purchased this Peavey DSC-4 Dual Clock Stereo Chorus pedal the moment I saw it to replace my Peavey CMC-1 Companded Chorus which had stopped working. This pedal not only performs the Companded Chorus, the most beautiful chorus I have ever heard, but it also performs a full wave chorus as well. Both choruses having separate controls for Depth and Rate. I only use the Companded Chorus function on this pedal for the moment. Once I get the CMC-1 repaired I will start playing around with the full wave chorus function. Mono in and Mono/Stereo out. The stereo outs are tied together, this means that both chorus effects go out on both outputs. Truly great pedals these are. Metal Enamel coated (bright day glow PINK to boot) casing that is absolutely stout. You probably won't break this thing with less than a plasma torch. Which if that's your thing, DON'T, I'll take it off your hands as a second "let's see what happens when we want to abuse gear and make noise" bit of kit.
