What's the difference between a guitar with 21, and 22 frets?

Question:You can hit a high D on the E string with a 22 fret - and some people bend up to the high E, giving you a full 2 octaves. Doesn't come up that often. It's the scale length that really matters - the longer Fender scale has a softer feel and the strings are under slightly less tension. The shorter Gibson scale requires slightly less finger stretch b/c the frets are a few millimeters closer together.

?!?!?
One more fret?
One more half tone in the scale?
A longer arm?

what exactly do you mean?

21 frets are more common to Fenders. Gibsons tend to like having 22 frets more.

Tonally speaking... you get an extra note on the board. You're stll a couple shy of two full octaves. It will depend a lot on the scale of the guitar (25.5, 24.75) and the actual construction of the neck (bolt/glue/set, maple/mahogany/rosewood) in terms of how it ends up sounding in practice, though.
