Understanding The Purpose Of The Guitar Neck Shim

Guitar Neck

Some guitars will just NOT change properly with the conventional approaches offered like the bridge saddles, nut declaring modifications and the capability to establish the bow (or lack thereof) of the neck itself. Including shims to the screw on neck may be essential to get the guitar to play effectively whatsoever places backwards and forwards the neck.

A nut shim functions as a spacer in between the nut and neck raising and also decreasing the distance between all of the strings at the lower end of the guitar, beginning at fret 1 and moving in the direction of the body of the guitar.

A neck pocket shim works as a spacer between the neck and also body, transforming the angle where the neck extends out far from the body.

Try to visualize the strings of your guitar as a level airplane as well as the fret board as an identical aircraft running beneath them. The angle of the leading plane which consists of the strings is managed by the setting of the tremolo and the nut. The angle of the lower aircraft which is the fret board is managed by the neck pocket of the body.

If your arrangement is excellent these 2 airplanes will have an equivalent distance in between them at any kind of point. If your guitar doesn’t look this way attempt changing the elevation of the tremolo itself first. This will generally take care of the problem unless you locate your activity ending up being too expensive or to reduced similarly across the size of the fret board. If changing the height of the tremolo fixes the issue but leaves you with too high or reduced of an action (distance in between the strings and fret board) after that you will require to consider utilizing a shim. You may wish to “obstruct” the tremolo prior to you start the shimming operation.

Shims can be discovered and utilized in 2 different locations of the neck. One is under the nut and also the various other is straight under the heel in the neck pocket of the body.

Nut shims are typically made out of one or more thin sheets of brass. Shims situated in the neck pocket are usually made out of a thin piece of wood. In either case you can produce your very own shim if needed by using a sheet of hefty supply paper such as a calling card. For shims in the neck pocket you could require to fold the paper stock 3-4 times to obtain the called for density needed, after that trim to fit appropriately.

First identify if the distance between the strings as well as fret board is to close right up against the nut itself. If this holds true after that add a shim under the nut and also elevate the tremolo by readjusting the tremolo messages till the strings are an equal range from the fret board down the entire size of the neck. If the distance between the strings and also the fret board situated right up against the nut is ALRIGHT after that you will have to position a shim in the neck pocket to correct your trouble as directed listed below.

If your strings are greater on the Reduced E side, place the shim in the neck pocket under the heel of the neck and also parallel with the length of the neck on the Low E side, which increases the whole neck down the Reduced E side when it is bolted on. Prior to doing this check the angle of the tremolo to make sure 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 contrary, as clarified over, by putting the shim alongside 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 certain it is level versus the body as well as not drifting at an angle.

If your strings end up being greater the closer they are to the body location the shim across the neck pocket in the long run closest to the neck pickup. This will certainly transform the various other end of the neck pocket right into a key factor and relocate the head stock towards the rear of the body decreasing the strings over the luxury frets.

If your strings come to be reduced across the high end stresses place the shim across completion of the neck pocket furthest away from the neck pick-up. This will certainly increase the headstock far from the rear of the body, increasing the hang from the end of the fret board, closest to the body.

In some circumstances you might find that you require the shim to elevate just one edge of both planes as described above. In these rare situations, make a smaller shim and area it in the appropriate location of the neck pocket. Certainly upon eliminating the nut from the neck or the neck from the body, if you locate a shim currently there
identify what action it was performing in the top place after that make the necessary modifications.

Shimming a guitar neck is absolutely an ART. Nevertheless, if you consider it medically, as angles versus an airplane, you can recognize the “just how and why” of readjusting a guitar neck by doing this.
