Precision/Tele Bass Style Control Plate
I had one of these made for a well known guitar builder, and ended up getting a couple more made in case there was any kind of demand.
It features two 3/8" holes for potentiometers or an output jack. The mounting holes are all countersunk, so that flat head or oval head mounting screws can be used.
Made from 14 gauge (2mm/0.075") stainless steel.
Available in a right handed or left handed configuration, with your choice of 4 finish options.
