MOD IDEA: would this make negative feedback of boss BF-2?

Postby scoop » 08 Jul 2018, 01:53

this is the full schematic

I figure this is the last opamp (buffer?) before the delay line goes to the resonance knob.

If I simply find a way to swap pins 2 and 3 of IC2 would that make the signal inverse?

Thanks for any advice!

Short answer,, NO.
longer answer; Quick fix mods without a deep understanding of how something works will just lead to tears.
Messing with pcbs is the fastest way to destroy a good working pedal.
If you want to fiddle with this circuit buy the parts and breadboard your dreams. :wink:

well luckily there is a bit of room in the BF-2, I could possibly fit a daughter board in that inverts in the path of the resonance
