Just finished up this project. It was a lot of fun to build, for some reason I love the projects with tons of components. This is the new DC version, I build the legacy version years ago. This thing rocks just like the legacy version.

I was able to calibrate the compressor, per the build guide.

The distortion trimmer is still giving me issues, the build guide seems to still reference the legacy build. I Just know that I am barely getting 1v on pin12 of IC 10.

Otherwise, a great project, I highly recommend.

Nice work! Looking forward to finishing mine as well….some day. It looks like the drill template ended up working out?
 
If I recall, on mine I tried really hard to follow the setup guide and ended up just tweaking it by ear. I have the real thing so was able to get it in the same ballpark just by feel. Plus it really depends on if you want to push a power amp or use this as an effect. Labs have a pretty wide swath of headroom.

What's your measurement setup?

I have my signal generator setup with the positive and negative of the probe are going to their respective test hole on the mainboard. Then I have my multimeter measuring the voltage at pin 12 of IC10.

Did you ever get this worked out? This is on my short list of pedals to build in the next year.
