OK, I've got one for you. What's the effect used by Elliott Randall on Steely Dan's song Green Earrings? The effect on the intro. Not the chorusy stuff in the middle (that's Skunk anyway), not the whooshing Mu Tron Bi-Phase at the end.

It's almost wha like, sliding greasily from note to note. But it's definitely not a wha. I've got a regular MuTron and I can't get the sound with that either. I spoke with Elliott and he only remembers using the Bi-Phase at the end, so let's help him and me out. TIA,

It sounds like a volume pedal and a slide with whatever comp and gain are already on there.
