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.
