I found what I thought to be the issue - I had popped a 1uf cap in where a 1nf should be, but in replacing the component I have somehow borked the entire thing. 1 step forward, 2 steps back.

Hmm I am having the exact same issue. I can't quite make sense of it as probing seems to indicate that the gain pot is connected as intended. I've reflowed, tried with and without the charge pump and nothing has changed. I've tried jumping across the gain pot pins and that didn't make a...

Yes the tayda quick order was the just one more thing here. I combined 50 BOMs and had 180 parts to order… I have to call this done now so I can get back to actually building pedals.

As far as grouping and merging there are no limits, but for the Tayda skus I think I grabbed up to 680uf or so. Above that would be manual purchasing. I am also dropping any voltage requirements as the skus I grabbed cover 95% of the use cases. For something high voltage you will need to do...

https://github.com/reghartner/bommer/ This code needs clean up and refactoring...I know it can be prettier and should have tests, but it works right now, and will be of use to you folks. Basically… - combines BOM pdfs into a master BOM - useful on its own if you don't use Tayda - Maps the...

I tried a few things even going as far as throwing a jfet buffer in front to try to mimic whatever the EUNA was doing to help, but nothing made a noticeable difference. I ended up ripping it all out and keeping the stock configuration after everyone's comments. I will just be happy tat the...

Apologies! Here is the schematic https://docs.pedalpcb.com/project/Sabbath.pdf and here are some pictures. Comparing the schematic to the perfboard layout the 1M pulldown resistor does seem to be missing. The fact that the buffer completely eliminates the noise makes me think this is just an...

I've run into dirt pedals that don't like buffers before them, but a Sabbra Caddabra clone I built on perfboard (https://effectslayouts.blogspot.com/2015/03/catalinbread-sabbra-cadabra.html) is very noisy without a buffer in front. I turn on my EUNA clone and the noise floor drops super low and...
