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.

Carl Martin Plexi-Tone
This is probably the biggest Marshall-in-a-box pedal out there (footprint-wise anyway). Originals use a +/- 12v supply with a transformer internally. I modified the power section with a +/-18v charge pump and will run off a normal +9v power supply. This saves room so you can use a smaller enclosure and gives more headroom to the effect. It is a buffered effect, so the In/Out pads go directly to the jacks. All switches marked in the layout are the footswitches. It should fit fine in a 1590BB with top mounted jacks.
