    Hi All,
    I want to make a stageboard for my ATS 120 combo amp. Here's the actual stageboard.
    My schematic without LED's is here:
    Clean, crunch and lead are momentary switches, and reverb & FX are on/off switches...push on, push off.
    I've built this pedal but without led's and would like to incorporate them into the circuit but don't know how.
    I found a schematic of a Hughes & Kettner TRIAMP footswitch and it has diodes in the resistors, or cap. Just switched, LED's, and diodes.
    It's a 9 PIN cable and one of the PINS carries a 22v lead.
    Can someone help with designing this board?

    I am planning to build one, too. Do you speak German?
