Q: Are there any other guitar scales outside the ranges provided that the Dual Notched Straightedge will work with?

A: Yes, the 22.75” scale used on Baby Taylor guitars (excluding the Big Baby Model), Squire Mini Stratocaster and some others will work perfectly with the F-25.5” side. Just place the second notch from the front over the nut and the notched straightedge will fit perfectly to your fretboard.
