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.
I love the smell of solder in the morning.

Re: Ibanez FL-305 Flanger trouble
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.

Re: Ibanez FL-305 Flanger trouble
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.
