The primary metric used to describe a guitar neck is the scale, which is the overall length of the strings from the nut to the bridge with the frets being placed proportionally according to the scale length so the smaller the scale, the tighter the spacing of the frets. There are also several sizes of fret wire available and traditional players often prefer thinner frets, and shredders liking thick frets. Thin frets are considered better for playing chords, while thick frets allow lead guitarists to bend notes with less effort. I use jumbo frets myself on a Strat plus and Ive got no complaints. IF you are trying out an electric for the first time spend some time talking to your dealer and trying out a range of instruments with differing fretwire and neck combinations – for example there are C necks, U necks, and V necks.
