Okay, So I have a Gretsch Duo Jet and I want to put in an effects loop.
I also want to get a buffer or stratoblaster. I think i understand how to wire that but...

My question is I cant seem to figure out how i should wire the effects loop with on a gretsch guitar.
Here is the schematic...

I have the tone POT version.

Thanks,
