SM2037 StewMac wiring jig for Jazz Bass (TM)

Hold your pots and switches in place while you solder. Everything is accurately spaced so you can trim the wires for an exact fit. Your wiring harness will fit neatly into the cavity with no fuss.

This is a ready-made jig with accurate spacing for brand name guitars from durable plywood that you'll use over and over again. "It's soooo much easier than trying to wire things up when they're sunken down in the control cavity!"
?Erick Coleman, guitar repairman and StewMac tech advisor

Soldering is easier and cleaner when using a wiring jig. You can work outside of the guitar cavity with clear access to the electronics, and you won't scorch the walls of the control cavity with a hot soldering iron.
