Fret slots are measured by a number that is specific to the fretboard size and material. This number is located on the fretboard near the nut, and will be preceded by the letter “F”.
The slot measurement can be found by looking at a fretboard that has been laid out with all the frets marked, and then measuring the distance in between the frets. The measurement will be in millimeters.
There are a few different ways to measure fret slots accurately. One way is to use a micrometer, which is a tool that can measure very small distances accurately.
Another way is to use a camera, which can take pictures of the fret slots and then measure the distances between them. Whichever method is used, it is important to make sure that the fret slots are measured in an even manner so that they can be averaged together.
The final step in measuring fret slots is to calculate the slot measurement using one of these methods. Once this number has been calculated, it can be used to order new frets or replace old ones on a guitar.
