NUT WIDTH OPTIONS
This is the smallest nut width and considered “Vintage” since most of the guitar makers in the 1950s and 60s used this size. Smaller hands will find this very comfortable as do players who mostly play rhythm.
Considered the standard size of the guitar industry for the last 30+ years, 1 11/16 Nut Width allows for what many consider to be the perfect balance between chording and soloing. This is the most popular Nut Width size.
For those with slightly larger hands or soloing techniques when a slightly wider string spacing is desirable, this is just the ticket! Some 80s shredder guitar companies used this size along with large frets to create a unique soloing feel. It also may remind you of how an acoustic guitar neck would feel.
This would be the Grand Daddy of Nut Widths. Giant hands will love this size as would people doing specialized guitar building and adding more strings to the neck.
