[SOLVED] FACE Melter trouble... Please HELP :(

[Arasek]

Hi guys, I am lost... This is not my first build, i have build 3 tube screamers and everyone work just fine. But this face melter is melting my brain right now.. I really dont know what to do now. Please help me find a solution.. Or at least post your PCB wich are working..

When i turn pedal on, i hear Loud 50HZ. Pots doesn't work. Even switch doesn't do anything. When turned off i can hear guitar playing.

There are few links to photos of PCB..
and documentation

Thank you !

Look at my PCB board Update above as temol has noted, this must be what you have done with the Jumper?

Yea this is excatly what i have done. I have marked wrong since its mirrored. :/

I would like to thank you all for your messages and help... The problem was in damaged pad under pot leg. LUCKILY it was just A->B spot so making jumper was really easy. Needles to say I have also cleaned solder-side board with toothbrush and Alcohol. And re-solder every single spot on it (which could also help, but don't know for sure). There was also problem with humming and beeping which was solved by different (isolated power supply in my pedalboard) power supply.

Conclusion:
Don't be a silly Billy like me. And work calmly with a clear mind, and If something goes wrong, get some sleep and try it next day otherwise you could make it even worse..

Here is small low q video of pedal.

Hi Awesome job!! could you post a close up picture of the finished board is possible.I just bought this pcb and I’m trying to figure out what the right parts to buy are. Im new to this and some of the parts are a little confusing for me. The parts have different voltages (as shown in picture) and im not sure which i need. Any help building this would be greatly appreciated

The parts have different voltages (as shown in picture) and im not sure which i need.

For the electrolytic capacitors on this build you would want 16V - 25V. Any voltage 16V or higher will work, but the physical size increases with voltage so higher voltage capacitors would be a tight fit.

Thank you so much would you happen to be able to point me in the right direction for the input/output/power supply parts? Ive seen some that are combined into one piece but I’m not sure if it would work or if it has to be individual to work with the pcb. Unfortunately I did not see those parts listed on the document and not sure what to search to find them to purchase them.
Thanks again very much appreciated the fast reply.
