Red Witch Moon Phaser - adding an LED via 4pdt

[ghostsauce]

I know a guy who has one and wants me to a put a status LED In it. Don't have the pedal from him yet but just doing a little research...  Gut shot!

Ok, this thing uses a 3pdt to achieve true bypass but all the poles are used up. Looks like I can grab a 4pdt and use that to solve this issue, correct? I can't figure out how they've got it wired based on the picture since I can't see where everything goes, but I can't think of any reason I couldn't get it to work. But maybe you guys can.

Looks like the bottom left hand lug is free, so depending on what the rest of the wires are for you might be able to add a LED there. Can't see how the switch is wired, but once you figure it out you might be able to rewire it with a LED using normal true bypass wiring.
