This has gotta be a simple one. Allows you to share some pedals between acoustic and electric while switching you input and output with one stomp. How would you wire this? 4PDT? I'm curious because I can't imagine it being terribly complex and I can certainly build this cheaper than $90 that he charges.

I think you could do it with a 4PDT with the pins aligned horizontally and numbered left to right like this -

1 2 3 4
5 6 7 8
9 10 11 12

1 = acoustic input
5 = send
9 = electric input
2 = acoustic output
6 = return
10 = electric output
7 = ground
3+10 and 11+2 connected to ground the input of the unused amp. If the LED is a bicolour (e.g. Green = acoustic, red = electric) pin 8 receives +9v via a current limiting resistor (1-10k), pin 4 to green anode, pin 12 to red anode, both cathodes grounded.
