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.

Cornish SS-2

With the G-2 fresh in our minds, I thought I'd draw up the SS-2 as well. This is set up for a 125B like the G-2 due to the footswitch board. The circuit itself is like an MXR Distortion + with a tone control and a gain recovery stage. Originals utilize 2, LM741 chips, but I've drawn it up for a LM1458 (which is a dual version of the 741) to make things a little easier and save space.

  2. I am really excited about this layout. I have a question regarding the layout above. Which is correct on the layout above for the 4.7N and 10N? Do they go up and down or side to side because the 2 diagrams are different. do they both go to drive 2? I really appreciate your help.

    1. The PCB version is different because I'm not tied to 0.1" spacing like I am with perf. The connections made are the same though. If you're building on perf follow the left layout. If you're etching a PCB follow the right.

  3. I finished creating this pedal. I built the buffer and connected them together just like the original. I like the 1458 instead of 2 LM741's. I am still boxing this but it sounds great. Thank you for your awesome Layout.

    1. Box film is what I had in mind, but you can use whatever you want.

  5. I finally finished this build with the buffer. It really sounds amazing. I decided to put it in true by pass rather than wire it inline like the original. The buffer is there if you hit the switch which keeps the tone correct. Here is a link to my build.

    2. Thank you so much for your complement. I really love this site. I etched the G2 and double buffer as well. Can't wait to build them. I have built both with Vero but it will be cool with PCB. Thank you again for your hard work.
