OK, I just came back from a gig where the other guitar player blew my head off with his sound. Several times I almost stopped playing just to listen to him... He was using two 20 watt mini amps, one tube and one SS. I walk over between songs and he has only three boxes on a mini pedal board: some kind of boutique overdrive, a stereo chorus and the this Mutron envelope filter thing. I ask him how he was getting this liquid volume swell type sound (thought maybe it was just his McCarty w/ pinkie on the knob) and he looks down at the Mutant and back up.
So, my question is - who uses an envelope filter and what type? I may need to get one of these things!!!
