Ground wire channels.

The hole drilled for the ground wires was going to be via a different route. Once I had the strings on and the rest of the hardware, plans changed. The angle through the bridge stud hole was too sharp so I opted for a side drill. It will require a MOP dot for concealment, but it'll work fine. A 1/8" bit works good for one wire but not two. I had to redrill the pickup-to-jack hole and increase it to a 3/16" bit. The bridge studs are drilled and look well centered. I had to be carful. I didn't want to go through to the back or into the tuner cavity on the back. I just need to test the jack cavity, mount the pickup for testing, and it should be ready for final sanding and pore filling.
