Frequently Asked Questions
What is the "Rule of 17.817" in guitar building?
The Rule of 17.817 is the mathematical constant (1 / (1 - 2^(-1/12)) ≈ 17.81715) used to calculate fret positions. Dividing the remaining scale length by 17.81715 produces the exact distance from the current fret to the next fret.
Why are Fender scale lengths (25.5") different from Gibson (24.75")?
Fender's longer 25.5-inch scale requires higher string tension to achieve standard pitch, producing the bright, snappy, and articulate tone characteristic of Strats and Teles. Gibson's shorter 24.75-inch scale has lower string tension, creating a warmer, rounder tone with easier string bending.
How does scale length affect bass guitar tone?
Electric basses typically use a 34" long scale length. Longer scale lengths increase string tension, which produces tighter, clearer low fundamentals on low E and low B strings without muddy flabbiness.
What is the best way to measure fret slots during neck fabrication?
Always measure fret positions cumulatively from the front face of the nut rather than step-by-step from fret to fret. Measuring fret-to-fret accumulates ruler reading errors at each step, ruining intonation across the neck.
