Q: My Gibson says 24.75" guitar scale. How come it doesn't work with MN804 (E-24.75)?

A: Gibson refers to 24 ¾" for their standard guitar scale, but since they've used fret spacing formula(s) different from the modern standard, Gibson uses the Rule of 18 for fret spacing while the rest of the industry uses the Rule of 17.817. This change in the calculation results in scale lengths shorter than a traditional 24 ¾" from most other makers. Gibson's modern boards end up the equivalent of a 24.57" scale length. The MN801 (G-Electric) Fret Shield is made specifically for Gibson electric guitar scales.


Q: How do I determine the scale length of my guitar?

A: How to determine your scale length depends on what tools you have on your bench. See below for different methods of measuring scale length based on the tools you can access. We have provided 3 ways below. 

1. Using the MusicNomad Tri-Beam Straight Edge (MN820), place the zero edge flush against the inside edge of the nut (see photo below)

and measure to the center of the 12th fret (see photo below).

If your scale length is one of the more common scale lengths, the center of the fret will align with one of the scale callouts on the ruler. If not, read measurement and then double it to calculate your guitar scale.

2. Using a tape measure or ruler, align the 1" mark with the inside edge of the nut (see photo below)

and measure to the center of the 12th fret (see photo below).

Take the difference between the measurement and 1" and double it to calculate your guitar scale.
3. If you are still unsure about your guitar scale, contact our Guitar Tech at tech@musicnomad.com and we will be happy to assist you.


Q: Where can I find replacement rubber bands to hold down my shield?

A: The rubber bands are size 16. You can use household rubber bands or hair ties. You can also buy them in bulk. Here is a link to find them on Amazon, CLICK HERE.


Q: How can I get my rubber bands to be fixed on one side?

A: You can tie a knot. Think of a water balloon at one end of the rubber band. On top of the knot, the short side, wrap over the tab and the rubber band will stay installed (see photo below).


Q: Will the Fret Shields fit guitars with more than 6 strings?

A: In the product bullet points and photos, the first and last fret lengths are provided.  To be able to identify if the Fret Shield that matches your guitar scale will fit a guitar with more than 6 strings, measure the length of your first and last frets and compare against the provided dimensions to determine fit.
