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 shim for P Bass

By

Verified Buyer


Popped the 0.5 degree shim in, set the action and it works better than ever. I got it done in about 45 min then played longer than I can remembr in recent memory after that. 'Wish I'd done it sooner.

Cheap quick way to transform any guitar... works great!

By

Verified Buyer


I've used these .5 shims for both a guitar and recently a bass and they really work nicely. Neither instrument was a fender, one was an Japanese Vantage guitar, and the other is an Aria Pro II pj bass and these shims fit those guitars just fine. The .5 shim goes a long way and should be fine for most applications. These shims made a huge impact on how these 2 instrument play now and i'm very pleased. Thanks to StewMac for always having what I need. I'm located in NJ and the shipping is always quick!

Full contact shim for  neck-body  angle  fine tune

My restoration of a Dan Armstrong guitar required shimming. The bass un drilled shims were ideal, I had total control over bolt hole placement. Magnificent.

Great fix for my string height issues.

By

Verified Buyer


The shim fit almost perfectly, I had to sand down the sides just a bit, but it dropped right into the neck pocket and resolved my height issue without losing any wood to wood contact. You can see my build/fix here - https://www.youtube.com/watch?v=ZaZtPjVIwHk

Bass Neck Shim

By

Verified Buyer


I tried to put my Leo Quan Original Badass bridge on my Fender Jazz Bass. With the height adjustment screws completely removed the action was still close to 1/2" off the fretboard. At first I thought the bridge would not work on my bass. I checked on StewMac and saw the neck shims for bass. The .5 degree shim was perfect!!! Now my bass has a Badass bridge and a nice low action.
These shims are worth every penny.

Super easy to use!

By

Verified Buyer


I have a Squire P Bass that the neck was not in line with the body. I had funky action and intonation issues and the bridge saddles were nearly bottomed out. I got a .5 degree shim and it was very easy to install. I shaped the shim as needed to fit so it wouldn't overhang the neck pocket. Now the neck is perfect in line with the body, the saddles are back up in a normal position and the action is nice and low.

Lowered my action

By

Verified Buyer


I was concerned the .25 shim wouldnt be enough to lower the extremely high action on my Squier Jaguar Bass (I added a high mass bridge) but it worked perfectly. In fact the. 5 would have been too thick. Yes it's a little pricey and on top of that theres another $10 in shipping but you'll be glad you ordered it once you see what it does for your high action.

Blanks not long enough

By

Verified Buyer


Folks at Stew Mac seem to want to think it's still the '50s, but a lot of basses today are not P&J. Many have extra long, 6 screw pockets and the blanks need to be about 50% longer to work with modern basses. Fine for stuff designed when fins on cars were in style, not so much for things designed in the internet age.

Worked Great!

By

Verified Buyer


The shim worked great on a bass that I converted to fretless - too much string buzz with the action set where I want it. The neck actually appears too straight even with the truss rod loosened all the way. I used a 0.50 degree unshaped shim (which I shaped for the neck pocket) oriented the opposite way compared to how it is shown in the instructional video, so the neck is tilted outward slightly, allowing the action to be lowered without buzzing. Much better than using business cards between the neck and neck pocket.
