And make sure you didn't plug in to the out. Easy to do when it's late and the pedal is down side up on the bench
With no led, check you switching with a DMM, check you power for reversed polarity(if wrong, check D100 for damage) and check led for orientation.
For the switch, power off, continuity/diode mode, you should have continuity between the middle row and the top and bottom rows, depending on switch position. It is possible to overheat the switches when soldering and bork them.
If all that checks out, post pics clear of both sides of the board please.
