Use an existing hole, or drill a new 9/32” hole in the pick guard

black wires) into the Hexpander on the rows marked VO and VI.

Note: a 250k linear-taper pot is preferred, but it will work with
a 250K audio-taper pot too. (regular guitar pots are audio-
taper) You will still be able to control MIDI volume if you use
an audio-taper pot, but mid-volume will not be at mid-scale.
