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.

perfect for my problem

I didn't thin 1 degree would have changed much on the neck. WRONG. I should have ordered the 1/2 degree. that would have been more enough to correct what i needed to correct. Stew MAc is a great company.

Fix your bass neck pitch, the right way!

The Stewmac neck shims are fantastic! Perfectly made with little trimming necessary. These really did the job of setting the neck pitch on my Fender Jazz and I think it also improved the timbre of the bass!

Neck shim

The shim fit my Fender Jazz Bass perfectly. I was able to get the action on the upper frets down where it is supposed to be. I plays WAY better.

Pricey, but works beautifully!

I didn't put these in myself, so instead, had my local guy drill and cut them to fit (purchased blank ones). I bought two 1-degrees, and one .5 degree, thinking I'd need all three, because I originally had bottomed-out saddles with action that was quite a bit higher than I prefer, and thought I'd need a good bit of angle adjustment. Turned out that I only needed the .5, which drastically lowered my Peavey's action, with tons of room to spare on the saddles. My tech had it done in no time, and painted the edges black to make it look like it's not there.

I don't really think I can give a 4 (instead of a 5 rating), even with the shims being a tad short to reach the end of the neck joint, because just one shim still worked very smoothly. Best part, is that, yes, no real gaps to worry about causing a "kink" or "ski jump" over time. Luckily, my neck is as straight as an arrow, but still...nice insurance policy! These shims aren't cheap for what they physically are, but they fixed my action dilemma perfectly and professionally...in my opinion, worth the money.

I used the .25 shim on a strat that was put together from spare parts and the action was way too high. This shim corrected the issue and now the neck is true and plays like butter after a basic setup! The guitar really resonates now! I'm extremely happy and have purchased more just to have on hand.

Brilliant idea

On my, Ibanez Mikro Bass, the bridge saddles were flat down to the bridge plate, and still the action was far too high. I fitted a .5 blank shim and was able to achieve a low, easy to play, action.
I was a bit careless when drilling the screw clearance holes, and split the shim length ways. However, I laid it in the neck recess and fitted the neck, all was OK.

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.

Put a few of the .25 in my Jazz Bass and the neck was more playable again.

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.
