From the post
Wanted to redo my old layout with board mounted pots. I've laid it out with the Presence control externally and the diodes on a DIP switch, though you could easily wire up an external toggle if you want. Should fit nicely in a 1590B. If you want the King of Tone, just but 2 in one box.
