Measure neck cavity depth.
Some of the newer Jet pickup cavities are shallower than other models.
The neck pickup cavity may need to be routed if it is at 1/2″ depth.
Measure the bridge cavity.
With the bridge cavity depth at 7/16″, a short bridge pickup is needed.
If necessary, route the neck cavity to proper depth.
Check the depth of the neck pickup.
The top of the pickup should be level with the pickup ring.
Insert the bottom shim into bridge cavity.
This is needed so the mounting screws have something to bite into.
Screw bottom shims into bridge and neck cavities. Then wire-up your pickups.
Place compression rubber over the bottom wooden shims.
These are needed for fine height adjustment.
Make sure both pickups are centered with both E strings before the
pickup mounting screws are installed.
Use pin vise with .078″ drill to drill pilot holes for mounting screws.
Notice angle of drill bit — Perpendicular to E stings for proper pickup angle.
Screw in the mounting screws.
Screw in the side filler-blocks.
Use mounting screws from stock pickups to mount filler blocks.
Install pickup rings.
String it up!
