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.

Power Brick

Here's a little utility board that could come in handy. It uses a MAX1044 or ICL7660 to convert +9v to both +18v and -9v. It's essentially the charge pump from the Klon Centaur. I've added a 10v zenner (1N4740) diode to protect the IC, but that's optional.

    1. You could easily tack this onto a project like Small Bear's power supply project. Here's that tutorial:

      There's a kit you can buy, but you could easily source the parts yourself. I'll see what I can come up with for a full project though.

    2. Just did a little research and there's no sense re-inventing the wheel. This Instructable fits the bill perfectly.

      It has outs for 5, 9 and 12 volts, though if I were building it, I would swap out the 7805 regulator for 5v and put in a 7818 for 18v.

  4. I didn't understand what it is. Sorry, I am very new on this. By the way, very nice blog, one of the best DIY pedal blogs (if not the best). Great work.

  5. Can I feed a normal +9/+18v pedal, and a -9v pedal at the same time, sharing ground without any problem? Like a positive ground fuzz face?
