This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Ross Compressor

Somehow I've not laid this classic out already, so here's the Ross Compressor. One of the most highly thought of (and therefore copied) compressors of all time. Should be an easy fit in a 1590B.

  1. Very cool! Any way you could post a version that uses an LM13700? Those 3080's are getting hard to find and expensive when you do. Thanks for all the hard work!

  2. I must agree. Most 3080's seem to be fakes these days.

  3. Actually, a lm13700 layout would be great.

  4. The CA3080 has been reissued and are no longer hard to find, I've just bought a few from smallbear electronics.

  5. Or you can use the converter here: http://effectslayouts.blogspot.mx/2015/11/lm13700-to-ca3080-conversion-board.html

  6. This layout is so tight I'm not sure one of those converter boards would work here. Good to know about the Smallbear part, but I've got some LM13700 on hand...Don't get me wrong though, I'm not complaining about the awesome efforts shown on this site, it's one of may favorites. Just an idea is all it was.

    1. Just put a socket in there and then you can likely fit the adapter board on top!

  7. I just finished this build...Oddly, my build sounds like a distortion pedal instead of a compressor, as in, if I run a clean signal in, and then turn on the pedal, I end up with distortion instead of compression. Any ideas?

  8. I built about 15 pedals in November and said time for a break...Then I saw this, had the 3080, the 5088's and built this instead of watching the Super Bowl. It was worth it! Another great board!
