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.

Menatone King of the Britains
Here's a Menatone design that emulates a Marshall JCM800. Like many Menatone circuits, the King of the Britains has had several iterations over the years. For this layout I went with the 6-knob version (and is essentially the same as the Electrictabs JCM800 emulator). I've laid it out specifically for a 125B enclosure with all the pots board mounted. Here's the schematic for reference. I would have liked to included trimmers for biasing the J201s, but there just wasn't enough room. So it's probably a good idea to socket the resistors feeding the drains and reference the schematic for voltages.
