Hi there,
I've got a Spring Reverb build here that works okay on battery power but not plugged into the DC-in jack. The LED does not come on at all. Bypass works fine. When plugged in via the power jack and turned on there's no output at all.
Any help would be greatly appreciated! Thanks a lot!

It looks like you’ve got your + wires on you dc jack backwards. What are you powering it with?

Annoyed grunt! I thought I searched the forum thoroughly before posting. Man I've been building kits for years and I've had two novice errors in as many builds. Swapped a 120R and a 10K resistor on a Large Beaver because I didn't use my multimeter... Never stop learning I guess!
So I swapped those two connector leads and the pedal works fine on DC-in now. Still no LED though. I reflowed it and tried another one with no change. Power supply is just a crappy One Spot I use for testing.

Most likely problem is that the the LED is in backwards....another newbie error (j/k ;)). If swapping it around doesn't help, it's probably bad or burned out, in which case you'll need to replace it.

Ah it was burned out. Seems a few from my big box of LEDs have oxidized or something. Thanks for all the help! It works great now!
