Ibanez FL-305 Flanger trouble

A guy brought me his FL-305 for a pot replacement. The pedal sounded awesome before I swapped the pot out, but now it's only passing dry signal. I know the flanging portion of the circuit (BBD delay, clock, and LFO) works because I get get it to self-oscillation. It just doesn't mix with dry signal. Does anyone here have a schematic, tech sheet, or the pedal itself? I can't find shit anywhere online-- I've asked around at various other forums and even put in requests to Analogman, Ronsound, and other guys that would have or sell schematics.

Have you recalibrated the bias? It may be neccessary after a pot change.
Other than that I don't think think there is a schematic around for that particular pedal, some gut shots might be useful I guess.

Nah, I adjusted the bias.
The problem was with the wet signal not being mixed back in. I figured it out. The previous owner had rewired the bad pot to pass wet signal again, instead of just replacing it. When I put the new one in, I used the same connections and ended up grounding the wet. Signal to lugs 1 and 3, ground to lug 2? WHOOPS. Ground is lug 1, signal is lugs 2 and 3.
