so now ive got this

i am going to find another widerange for the neck,get some 1 megs pots and my other idea is to put a pedal into the lower cavity.
i was thinking a danelectro french toast, as i love the pedal and its probly small enough to fit in.I already have one on my pedal board but i dont really want to hack that up so ill try to find another one cheap.
Or the other option would be a fuzz face clone or something(i just want a simple fuzz small enough to fit in)
my question is how hard would it be to wire in the pedal to the guitar circuit? i will have all the pedal controls on the lower horn.
Is it only a matter of changing the input/ouputs and maybe the on/off switch?
has anyone done this with another pedal? wiring diagrams that would help
thanks heaps.
