By ProsthetaExcel spreadsheet for calculating up to 36 frets derived from a single scale length. Measurements calculated in both Imperial and Metric. No compensation.
Calculating the exact positioning and spacing for strings across the nut can be a pain....by inputting your nut width, fretboard edge spacing and string gauges, this spreadsheet automagically outputs all the information you need to create a proportionally-spaced nut! Awesomes.
