The wah works great on either kind of power, but the LED only lights when I use a battery. Not a show-stopper but I'd like to get it sorted out.

Plugged in, I get 9v across two lugs of the DC jack but only 6 or 7v across another pair. The power supply is putting out 9v.
On battery, I get 9v across both pairs.
(The third combination of lugs properly reads 0v all the time.)

I've tried reflowing the solder and also removed the little pieces of wire used to reinforce the jack>PCB connection (as suggested here: http://www.byocelectronics.com/board/viewtopic.php?f=33&t=11206 just in case they were shorting something.
Its a great idea though, those little anchors, for a part that's probably gonna see some kind of stress plugging and unplugging. That was a really helpful tutorial for getting the jack to sit properly behind the hole in the enclosure.

Tested with the board both in and out of the pedal so it's not shorting on the enclosure.

Switch is wired for the LED as per stephen's other sticky: http://www.byocelectronics.com/board/viewtopic.php?f=33&t=11727

Cool wah and fun to tweak, just want it to glow a little!
Any suggestions received with gratitude!

You've probably connected the LED's anode to the wrong +9V connection on the PCB. Switch it to the other one and you should be good to go.

Hey thanks so much, Stephen. That was exactly the problem.

And I learned why there are 2 (+) lugs on the DC jack while I was at it!
