Graph Tech TUSQ 1/4" Nut Blanks

When fitting a TUSQ saddle you may need to adjust the dimensions slightly to get it perfectly matched to the guitar.

It’s best to do this adjusting by rubbing the nut on fine sandpaper (240 or 400 grit) on a hard surface. This will help keep the lines of the nut straight and square.

Radius
The radius of the saddle should match the radius of the fingerboard. If you are unsure you can check this with a Radius Gauge Set and change the radius if needed.

Thickness
Sand the sides of the saddle until it matches the width of the slot in the bridge, take a little off at a time until it’s a snug fit in the slot.

Length
Once the saddle fits in the saddle slot in the bridge check the length compared to the saddle slot. If it’s too long you need to sand a little off each end until it’s the right length, then round off the ends.

Height
The height of the saddle will play a big role in the setup of the guitar. It’s important that the saddle be at the correct height to make the action comfortable.

The easiest way to adjust the height of the saddle is to string up the guitar with the saddle at its full height, then measure the action at the 12th fret.

Measure from the bottom of the E strings to the top of the 12th fret. This measurement should be around 2.0mm on the treble side and 2.5mm on the bass side of an acoustic steel string guitar. If it is too high you need to adjust the saddle height to get it right.
