That's really odd. Does it make that noise in the bypassed position as well? With IC1 pulled? The fact that there's noise on your...

I also think that the blank space above the design is a clue. Make sure you don't have an element that is outside of your artwork...

Plug for the MasFX DIY tower thingie (https://mas-effects.com/tower/), if you're building a lot of pedals this thing is awesome. It has...

What a beaut, I love the hand-drawn traces. Has someone been in there already to replace the op-amps? Those look like they're date...

What do your voltages measure now? Do you get something closer to 9V on your 9V rail, or is it still ~7.7V? Is your VREF closer to 1/2...

re:VREF An audio signal swings both positive and negative voltage relative to ground. An op-amp can't amplify a voltage below the...

Agree you need to check R101 and R102. The numbers on your ICs tell me that your VREF is totally wrong. Am I reading correctly in the...

Oh, based on the schematic that looks expected. It looks like that half of the dual op-amp isn't used, so it's all just grounded to...

I have to underline the advice about the audio probe, in my (limited) experience it's been the most useful tool for diagnosing issues on...

I have a special place in my heart for organic polymer caps, because those are, in a way, what got me into DIY audio electronics...

To hold the excess flux in place? But seriously, more than likely to take some high end out.

WE BUILT IT SHITTY

https://forum.pedalpcb.com/threads/pitfalls-and-tips-designing-effects-pcbs.28072/ Symmetry is over-rated. Ease of build is under-rated.

Have you tried an audio probe, to see where the "good" signal dies and you pick up the noise? That's a super handy way to help narrow...

Great post! To share what I feel is most important. Opinions and assholes etc.. Create standards for your builds. 6-knob and 4-knob...
