StewMac Neck Shims for Bass

About This Item

Tapered maple shims used to change the angle of a bolt-on neck.

To change the angle of a bolt-on neck, players and repair shops have used shims for years. We've seen everything from matchbook covers to guitar picks stuck in neck joints.

Those kinds of shims create an unwanted gap under the heel of the neck: a dead air space where humidity condenses to swell the wood. As Dan Erlewine describes in his Guitar Player Repair Guide: "This gap may cause an upward kink in the neck. And many players feel they lose tone unless firm contact is maintained between the neck and the body."

Dan creates tapered shims that cover the entire heel of the neck—with these ready-made shims, that work is done for you. Attention, repair shops: making a quality shim takes time! Keep these on hand for a quick turnaround on this common repair.

"My Jazzmaster needed a better string break angle over the bridge. The 0.5-degree shim let me raise the bridge to the height I needed. And it fit the neck pocket perfectly."
—Erick Coleman, guitar repairman and StewMac tech advisor

Full contact and precisely tapered: we have 3 different degrees for changing the pitch of any bolt-on neck.
  • 0.25-degree shim offers the most versatility. Stacking them will let you really dial in the neck angle you're after.
  • 0.5-degree shim is the one you'll reach for most often. It works great on Fender and many other solidbodies.
  • 1-degree shim is great for basses with a post mounted bridge.

Taper specs (approximate)
0.25-degree shim tapers from 0.030" to 0.019" (0.76mm to 0.48mm)
0.5-degree shim tapers from 0.028" to 0.008" (0.71mm to 0.20mm)
1-degree shim tapers from 0.060" to 0.010" (1.52mm to 0.25mm)

Dimensions
Shaped: 2-1/2" x 3-7/8" (63.50mm x 98.43mm)
Blank: 2-3/4" x 3-7/8" (69.86mm x 98.43mm)

Shaped shims fit most neck pockets with a rounded heel.

Blank shims were designed for odd screw spacings, smaller neck pockets, and custom designs like the Fender Micro-Tilt™.

The Shop Set of 12 includes one each of every size, shape and taper:
3 shaped shims for guitar
3 shaped for bass
3 blank shims for guitar
3 blank shims for bass

Made of solid maple to match the neck.

Bass neck shim blank

Had trouble w shim cracking when drilling but it fixed my friends bass which now has a pro setup. Before the shim the action couldn't be setup properly at the bridge saddles.

Easy to work with, but I am making a jig to make my own custom sizes. from better (drier) wood.

This was painless, and fairly easy. I used a small gasket punch to enlarge two holes and add two, so it would fit an 1990s Ibanez bass that I fell in love with 8 or 9 years ago, and now everyone that plays my RD 747 wants the RD 707 because they are one of the best values in a fine Japanese passive electric bass guitar that can be had. Some sanding, and some coloring to color the edge of the shim makes it less obvious, and the 1 degree cocks a 34" scale neck back maybe 3/8" at the nut, and raises the heel about .075". Sorry, for placing the Stewmac side down, but when someone takes that neck off, it's facing up now, so they will see it, very first thing.

Well crafted, terrible fit.

When it arrived it seemed to look really good and be of the utmost quality. Supposedly meant to fit any standard Fender bass, went to out it on my MIM precision bass and it was too big. Had to file down the sides just to slide it into the slot, and then it was about a quarter inch too long. Trying to use an exacto knife to cut that down ended up cracking it by one of the holes for the neck screw, and the decrease in length increased the angle so it was no longer 1°. It would have helped if a thickness of the shim at it's thickest point was included in the product description so as to accurately gauge the change in angle of the neck. Won't be buying again.

If You Have to Shim....

By

Verified Buyer


I bought this for my Musicman bass after I took the neck off.
The factory had put a lame piece of plastic as a shim.
With a little sanding the stew-mac maple shim fit perfect.
The bass plays better

Awesome product!

Needed to shim the neck on a vintage Japanese p style bass and these certainly did the trick. If you have ever burnt up valuable time trying to shim up a neck using the trial and error method and with whatever oddball material you had on hand it is time for you to throw away the strips of plastic and the playing cards and rejoice! With very little alteration to the shim itself these are a perfect fit.

Quick, Quality Fix for Neck Angle Issues

By

Verified Buyer


The neck angle on my Fender PBass was off after a bridge upgrade. I couldn't get the strings down to a playable height. I purchased a .50 deg & .25 deg shims, which were an almost perfect drop in fit. The .25 deg shim wound up being the perfect solution. Minor shaping was required for a perfect fit. Solved the problem.

Well made and accurate!

I bought the variety pack of shims (no holes, .25, .5 and .1 degree) to adjust a bass neck. This is my first time with these so, the only issue I had was drilling the holes since the thinness of the wood makes them prone to cracking when cutting or drilling. Maybe sandwich them between two pieces of wood and/or tape would've prevented them from cracking while drilling? I also used a utility knife to cut them down to size which worked. Otherwise, got it done and they worked perfectly! Maybe some instructions or suggestions on drilling or cutting would be beneficial.
