Thanks, I was actually thinking of just adding a 9v DC jack (powered by Voodoo Lab Pedal Power 2 Plus) and doing it that way, considering I can't find anything on (safely) tapping into the 120v supply from the wall to power the LEDs. I DID actually install an IEC power jack on the side so that it's wired for 3-prong cords, a feature that I wanted in order to more easily swap pedals out on the road if one goes bad. Check it out:
I discovered I can leave the stock DPDT switches and still wire up LEDs (I'm using special 9-12v LEDs that have the resistors built in, so I don't have to purchase separate resistors). I'm eventually going to be running it in a loop, so I'm not worried about doing a true-bypass mod to it anymore.
Thanks for the tips!
