Would also be great is there was a build doc. Site says "coming soon" for over a year

Thread 'Important: Supplying Pictures when an Issue arises with a PCB Build !!!'

Jun 17, 2021

I have to raise this ongoing issue when Members ask for Help with an Issue with their Build.
I keep repeating this saying '' Pictures are worth a Thousand Words'' !!!
Please supply Pictures of PCB & ALL connections ( Footswitch, Input & Output Jacks, Power Jack ) to it along with a clear explanation of the Issue with your Build in the Troubleshooting Forum!
You will save a lot of Back & Forth guessing from the Help available to you if we can see the actual Build!
This will result in a quicker & less stressful environment!

Most of us here are full send.... Build docs here are really just a bill of materials and a drill template.... it's not easy for the beginners at first... What doesn't kill you makes you stronger. Post good clear pictures of your build and we will take a peak at anything obvious and try to help.
I suggest take pics of it wired up in enclosure.... then remove from enclosure... bend up your pots and take good pics of back of board.

I would first take the time to go through your build and clean it up a bit. Trim the leads shorter and make sure you don't have any exposed wire, like the purple wire going to the output solder pad. Then I would mess around with the ribbon wire going to the switch. Poke at it while the trem is on and see if it changes. You have something shorting and it is grounding out the LDR while it is on. Go through and clean up your board and that will likely fix the issue.

I notice that the LED/LDR are uncovered. They need to be wrapped with something non-conducting & light proof (eg shrink wrap) for the trem to work. The pulsing LED is a good sign.
Hope you get it working.

I don’t think that’s true.

I’ve built a couple of these without any covering on the ldr and they work fine. (As long as the enclosure cover is on).
