How to reduce the noise with my Thor build ?

[solderman]

For what it's worth, the two Thor pedals I've personally built using the official PCB layout have not had any noise issues.

Yes I am sure that a lot of the issue is due to what I've (not) done...I have used my own layout... and as you can read, there are lots of little things to fix  ! I will check this on sunday

Hi just remembered that I had the same type of problem with a low gain OP amp dist. By chanse I eound a sloppy solder joint. It conducted but created hizzy noise. BTW sheelding the OUT will only benefit the next pedal or Amp.
