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.

Neck Shims for Bass

By

Verified Buyer


The .025 shim was just the right thickness for an American Standard Jazz Bass. Very little trimming required for a fine fit. Managed to lower string settings to below Fender guidelines. (Player has a reasonable light touch.) The the tone and sustain, I do believe improved considerably. (Your mileage may vary.) Great and conveinent product.

The perfect fix for a poor neck angle

By

Verified Buyer


My tune-o-matic bridge was bottomed out and action was still too high. I used the blank bass shim since the neck pocket was an odd shape. Got the shape perfectly in about 10 minutes. Tip: If you don't have a drill press to enlarge the holes: use a round file. Worked perfectly and I did not crack the shim.

Just what my 2018 Fender American Original 60's Jazz Bass needed to make the action right. Perfectly made and it fit snug.

Very pleased with my purchase. It fits perfectly and does a very good job. I bought a set of three, and the middle one was just perfect.

Fixed Action on My J Type Bass

By

Verified Buyer


The bridge saddles were bottomed out and the action was still to high for my taste. Installing the 0.5 degree shim allowed me to get the action just right. The saddles are also now at a good height to keep the strings tight against the saddles. I did have to drill new holes and trim the shim to fit. Trimming was easy using scissors. Like others have said, they are pricey but just try making your own.

What a remarkable difference!!!

I used business cards for decades to shim my bass necks when needed. I thought I would give this a try. I pulled the business card shim out, trimmed these blank shims to fit...gently drilled holes in the .25 shim piece, put it in...and WHAAATT! have I been missing!! The tone totally cleared up and became present and clean in comparison to what this bass was doing not 15 minutes ago!! And it is exactly like the air is gone from the notes and the notes are solid! I'm blown away!...
That's all I have to say!

A must have........

I purchased the 3 shim pack(.25,.50, 1) for Fender basses. I wasn't sure what to use on my '70's Aria Fretless P-Bass copy. I had run out of bridge adjustment. I installed the .50 shim and that did the trick. was able to finish dialing in the action.
After this I pulled out an old Aria Diamond Bass. Always loved the body style of this but could never get the action to a workable state. It's a hollow body with a bolt on neck and floating bridge. Just had to shave the 1.0 shim a bit to fit the pocket. Installed the shim and neck. With a little adjustment at the bridge, the action is perfect. These shims are well worth the price :-)

Did the trick!

I ordered .5 and .25 degree shims for my 5-string J kit bass build. Before adding just the .25 shim, the string action was too high even after setting the truss rod and bottoming the saddles of the Hipshot bridge.

Add mentioned above, I ended up only needing the .25 shim. Even though my build is a 5-string and the body's neck pocket is, accordingly, a bit wider than is the shim, the shim still worked after making its 4 holes a bit wider.

The shim added just enough angle at the base of the neck so that I now have tolerably low action and a good radius profile in the bridge saddles.

For those of you who might wince over the price of these shims, consider the time/tools/hassle of trying to make one of these yourself. These are made to ensure that there's solid contact between the neck and body - which won't happen using a few matchsticks, guitar picks, or random pieces of cardboard as shims.

If you've run into the action height issue I described above, I highly recommend checking these out.
