This template for routing the bridge pick-up in a Jazz Bass body is made from 5mm transparant acrylic allowing you to see the body while you work.

The center lines on the routing template help correctly place the template on the body. Attach the template with a few pieces of double sided tape, select a template router bit and you are ready to go.

Standard depth for the bridge pick-up cavity in a jazz bass body is 3/4 inch or 19mm. Some aftermarket pick-up require more room.
