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.

MI Audio Blues Pro

Here's a nice little overdrive circuit from MI Audio. This reflects the 2nd version of the Blues Pro, but if you want to make version 1, just jump pads 1 and 2 of each switch respectively. Should fit nicely in a 1590B.


  1. Verified! Had to use tl072 (no 4558's atm), and all linear pots. I need to do some shopping, apparently.

  2. Can I use 2.2nF capacitor to replace the 1.5nF?

  3. this ones awesome..worked first time ��
