POT CONFIGURATIONS

There are two spots for the FILTER pot. Use one or the other depending on

whether you’re making a 3 or 4 pot version.
The filter control works backwards

in the three-pot configuration,

with the tone becoming brighter

when turned clockwise (which actually

makes much more sense to us,

but whatever). If you want

it as per the original you’ll have

to wire the pot in reverse and 

use a reverse log taper.

NOTE: The above only applies if

your PCB has round holes fo

the toggle switch. This has

been fixed on boards with slots.
