Graph Tech Ghost - Manual (Page 17)

The ghost® boards are small -- about the size of a match
box -- so they will fit inside the control cavity of most
guitars without any routing. You must decide which
arrangement is best for your particular instrument.
To locate pots and switches, lay out their flat washers on
the top of the guitar and arrange them until they look
right, then trace the center of each washer to mark where
to drill the hole. Before you drill, make sure there is room
for the component inside the cavity behind the mark.
