Ok,  led works now. That's progess!

Thanks somnif.

I'm gonna swap out the LED and the resistor and see what happens.

I also tried connecting my in and out alligator clips and I get signal passing with the switch in either position. With a board connected, i get clear signal in one position (same as if i plug straight into my amp) and very very faint signal in the other position.

Also I'm never sure which lugs to use on the 9v jack. Can someone straighten me out on that?

100 ohm is a bit low for 9V through an LED. That would move 90mA and .81 amps of current. Its entirely possible you fried the LED I'm afraid.

Oh shoot. What value do you suggest?

Plus I had to giggle at the prospect of troubleshooting a troubleshooting box :-)

I thought the same thing before posting.

I double checked the aforementioned items. The in and out jack connections aren't touching. I reoriented each and tightened the nuts to avoid this calamity.

The hot and ground connections from the barrel jack are hooked up to the board correctly. The wires are slightly crossed under the board making them look backwards.

I'm gonna go through and double check all my connections again, plus look for bad solder joints too

hi y'all, my name is Will. I've been lurking here for a couple of months. I'm very dangerous with a soldering iron and good at assembling projects that don't work. I'm constantly trying to learn stuff and have enjoyed reading posts here.

Last year I got back into pedal building after not doing any electronics projects for a few years. I botched an amp build a few years back thinking i was hot shit and then got discouraged. I've purchased a buttload of madbean boards but haven't assembled any yet. Once I stray from a kit, things tend to not work so well. Anyway, nice to "meet" you all!

Hi, I tried building a test box and it doesn't work. I'm using a Rullywow 3PDT board for my switch. I thought I had everything hooked up correctly, but I guess not. Here's what I know so far:

1. The LED never lights up in either switch position.
2. I don't know what value to use for the CLR resistor. I think I used a 100ohm resistor.
3. I get 9v across the barrel jack lugs, on the pcb connection at the other end of the wires connected to the barrel jack, and at the end of the alligator clips going to the circuit I wish to test.
4. In one switch position, I get signal to my amp. In the other position, no signal.

I hope I made a silly goof here. Any help would be greatly appreciated. Thanks!
