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.

Nobels ODR-1

Got a request for this one. It's an interesting variation of the Tube Screamer circuit, but with a lot of changes and modifications. There's an optional boost switch you can include if you like that's not apart of the original. If you don't want to include it, just don't populate the 270Ω resistor and 2.2uF connected to the Boost Switch 1 pad. Here's the schematic for reference.

    Would love to see the noble mods in more detail. Dont suppose you have a higher rez version of the schematic anywhere? Cant read the values on this one.

    1. I think PostImage ate the resolution. Re-uploaded and it should be better now.

  2. Good posting.

    Is possible to you provide some schematics for us? I think that it could help me to print out these layouts.

    Thank you and good job.

    3. I don't share my project files, but there is a scaled PDF of this and all layouts in the Transfer Image Library tab at the top of the page.

    1. Fixed that along with a couple other errors. Should be good to go now. Thanks to greenskull over on FSB for finding them.
