Face Melter not working :(

So I finally put my face melter pedal together and I sadly failed hard. Its not making any sound and the only thing that works is the foot switch led and another led at the top of the board next to the grounds for the jacks. The 2 leds on the middle of the board are not soldered on but they are making contact like they would on an arduino when I test stuff before soldering. Besides that all my contacts are in place although not perfect they should be good enough to allow the pedal to work.

I have clue what i did wrong, does anyone happen to notice something thats not in the right place? I can add some close up pics if needed. Im hoping I didn’t fry the board itself 🤞🏻🤦🏻

(Moved this post from my face melter post to here as mentioned by chuckdbones since this is the trouble shooting section)

I would start by checking voltage at the pads of the LED’s in question. Are the bent legs of the LED making contact with anything? I would also reflow most of the joints on the top-half of the pcb. Some of the joints look like they could be cold. Also, is there any solder at the center lug of the footswitch? And the connectors you used for the pots; not a horrible idea, but I would double check that the exposed metal tabs on the sides of the plastic housings are not grounding out against any joints…

Thanks for the tips!! :) ill look into that stuff, the led legs are not touching anything just looks like that from the angle of the picture. I have a multimeter but I have zero experience with using it. Im more worried that i may have cooked the board. I leave my solder tip (low temp) on the contact and the wire for about 8 seconds and then flow the solder onto it. Thats how I was taught to do it but maybe this is totally the wrong way to do it lol.

Thanks for the reply :) I had to wire it that way do to the complications of my custom enclosure (the pcb was made for specific drill template that wasn’t the same as the original p melter pedal). That was the only way I could fit it inside although I wish I could have just mounted the pots to the board and used wired for the switch like Ive seen in many build posts.

Is is that important to copy the appearance of the Pu55y Melter exactly?

Since you get nothing in bypass mode, then focus on the wiring to the jacks & switch. Looks like the yellow & purple wires are on the wrong jack terminals. Move them both over one terminal.

Thanks! ill try that if i can manage to get the wires back off now lol

Take the easy path and just cut the wires off next to the terminals.

If you're not soldering the pots to the board, then it would be a good idea to buy pots with solder lugs instead of PC pins. I'm getting the impression this is your first build.

Absolutely my first build hehe. Ive done lots of Arduino stuff in the past but never anything like this.

Do you know how to remove the wire remnants from the board without wrecking the board?

Not really I do have one of those cheap solder suckers but Im not great at using them. Sometimes I can get parts back off the board but theres high potential that i will wreck the board by melting a bunch of stuff. I practiced on a few old mother board and desoldered everything on them but i burnt the board pretty bad in the process.
