Understanding The Purpose Of The Guitar Neck Shim

Guitar Neck

Some guitars will certainly simply NOT adjust appropriately with the typical approaches readily available like the bridge saddles, nut filing changes as well as the capability to set the bow (or do not have thereof) of the neck itself. Including shims to the screw on neck may be necessary to obtain the guitar to play correctly in any way areas up and down the neck.

A nut shim serves as a spacer between the nut and also neck raising and also reducing the range in between all of the strings at the lower end of the guitar, starting at fret 1 and also moving towards the body of the guitar.

A neck pocket shim serves as a spacer in between the neck and also body, altering the angle from which the neck protrudes out away from the body.

Try to picture the strings of your guitar as a flat plane and also the fret board as an identical plane running beneath them. The angle of the leading airplane which consists of the strings is regulated by the position of the tremolo as well as the nut. The angle of the reduced airplane which is the fret board is controlled by the neck pocket of the body.

If your arrangement is perfect these 2 aircrafts will have an equivalent distance in between them at any factor. If your guitar doesn’t look this way attempt readjusting the height of the tremolo itself initially. This will normally care for the problem unless you find your activity becoming too high or to low just as across the size of the fret board. If changing the elevation of the tremolo corrects the issue but leaves you with too high or low of an action (range in between the strings and worry board) after that you will need to consider utilizing a shim. You might wish to “block” the tremolo prior to you start the shimming operation.

Shims can be discovered as well as used in two various areas of the neck. One is under the nut as well as the various other is straight under the heel in the neck pocket of the body.

Nut shims are usually constructed out of several thin sheets of brass. Shims situated in the neck pocket are typically made out of a thin piece of timber. In either instance you can create your own shim if required by utilizing a sheet of hefty stock paper such as a business card. For shims in the neck pocket you may require to fold up the paper supply 3-4 times to get the called for density required, then trim to fit appropriately.

First figure out if the distance in between the strings and also stress board is to shut right up against the nut itself. If this is the case after that add a shim under the nut and increase the tremolo by readjusting the tremolo messages till the strings are an equivalent range from the fret board down the whole length of the neck. If the distance between the strings as well as the fret board located right up against the nut is OKAY then you will have to place a shim in the neck pocket to remedy your trouble as directed below.

If your strings are higher on the Low E side, position the shim in the neck pocket under the heel of the neck and also parallel with the size of the neck on the Low E side, which elevates the entire neck down the Low E side when it is bolted on. Before doing this check the angle of the tremolo to ensure it is level against the body and also not floating at an angle.

If your strings are greater on the High E side do the opposite, as clarified over, by positioning the shim parallel to the neck on the High E side in the neck pocket. Once more prior to doing this check the angle of the tremolo to make sure it is flat against the body and also not drifting at an angle.

If your strings become higher the closer they are to the body place the shim across the neck pocket in the long run closest to the neck pick-up. This will turn the other end of the neck pocket into a pivot point as well as move the head stock towards the back of the body reducing the strings over the luxury frets.

If your strings end up being lower across the high-end stresses location the shim across the end of the neck pocket outermost far from the neck pickup. This will elevate the headstock far from the rear of the body, raising the hang from the end of the fret board, closest to the body.

In some instances you might discover that you need the shim to elevate only one corner of the two aircrafts as described above. In these rare cases, make a smaller sized shim and also area it in the appropriate area of the neck pocket. Naturally upon getting rid of the nut from the neck or the neck from the body, if you discover a shim currently there
determine what action it was performing in the first place then make the essential improvements.

Shimming a guitar neck is certainly an ART. Nevertheless, if you look at it scientifically, as angles against a plane, you can recognize the “just how and why” of readjusting a guitar neck by doing this.
