StewMac Bass Neck Shims for Bolt-on Necks, Made of Solid Maple, Shaped, Set of 3

The StewMac Bass Neck Shims are a set of three shims made of solid maple that are designed to be used for bolt-on necks of Fender bass guitars. They can be trimmed to fit the contour of the pocket and come in a set of 1, 0.5 and 0.25 shims. In terms of compatibility, they work well with Fender Standard P-Basses and guitars based on Fender specs. The shims have a smooth finish and are well-planed for flatness, and the screw holes line up well with Fender-sized 4-bold necks. According to reviews, they make shimming a neck easy and offer no negative impact on tone. They are also portable as they can be easily trimmed using household scissors. One user noted that they were expensive, but they worked very well. Another user found them overpriced for what they are, but the quality of the build was appreciated. However, one user mentioned that they were not suitable for an Ibanez bass neck.
