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.

Idiot Box Effects Blower Box

Here's a pretty cool bass distortion based on the RAT. The normal filter section on a RAT is replaced with a passive baxandall network. It was traced by FSB member p.eat and the schematic I based this layout from was drawn by johnk.

  1. This is verified and sounds great. I used a LM308AH metal can IC.

    2. Lug 2 on the Volume pot is the Out. The layout's been verified, so double check all your connections and look out for jumps, etc.

  7. Hi! Build one and it sounds realy good but on lower gain settings (about 1/4) and with volume full on it sound quieter then uneffected bass. Is it some mistake or them all work that way? first i were thinking that its some problem with 201, but i tried different ones (and even 5457) - all the same. Tweaking bias is not solve problem too. Has anyone any ideas?
