Any neat trimpots to play around with inside this thing? I kinda want that Paul Gilbert "paul vs. Godzilla" crazy sound, which i know is a modded flanger.
Don't think I've ever seen a schem for a BF-3. Unlikely there will be trimpots to do anything useful... The ones on the earlier pedals (BF-2, CH-2, etc) are there to set the BBD bias and clock timing.
THe factory settings on the earlier ones are the only settings that really work and you need a scope to get them set - playing around with them can cause problems.
