The owner of this Jag was playing around with the setup and found the bridge height he liked that would allow enough down pressure to hold the strings on the saddle. At this height, the action was sky high making it tough to play. He brought it by the shop and I made a tapered full-contact shim to increase the neck angle over the body. These shims are much more involved to fabricate when compared to the common simple shim in the back of the neck pocket. Being a full contact shim, it eliminates any empty space in the neck joint and theoretically improves sustain. A full shim also better supports the neck and helps prevent the common fingerboard rise over the body (aka "ski jump") that can be caused by smaller step shims.
Also note that I had to add foam under the pickups in order to raise them up to the new neck set.
