Don't know about other people, but I need 24 frets cause I play a bunch of solos that use the last 2 frets.
It's also hard to play fingertapping solos when 2 notes are always missing.
Actually, I wish somebody made a 27 fret guitar cause I've got songs where I have to use the pickup as an extra fret to play a high G note.
22 fret guitars just seem like half the instrument is missing or something.
It's kinda like, would you buy a guitar that couldn't play a low E note?
No way.
So why buy a guitar that won't play a high E note?
