Rat 2 Mod Question

[Brushthrower]

Hey all,

I was going to try out a little diode-switch mod on my Proco Rat 2 pedal but I cracked it open and found not two but four diodes (aside from the 1n4001). Could anybody tell me which of these are the clipping diodes, or are they all?





Thanks!

Nevermind...figured out. Trial and error is my Scientific Method.  If anyone else is curious it's the two on the left next to the electrolytic cap.
