Haha, as cool as I think a guitar like that would be (because it would be)...
My post was mostly to highlight that often with questions like that, with the nature of "why not make ___ bigger/longer/more etc." there's ALWAYS going to be a bit of arbitrariness in the decision, and no matter HOW many frets something has you can ask "why not a few more?"
Of course, unless you do my idea... and as cool as that would be... who REALLY wants that :laugh2: In other words, if Fender had made the standard for fretboards 24 frets in the 50s, someone would be wondering why they didn't go to 25
IMO frets should always be smaller though (I can bend just fine with smaller frets and they get in the way less), but for the semitone idea, I almost wonder if frets should just be eliminated completely (oh wait someone beat me to that), that way you can pull off theoretically any infinitecimally divisible interval at will
That would basically put us in an "ancient technology" doghouse bass with a long fretboard, tiny body, and a piezo pickup :laugh2:
And do we REALLY want to play that? (maybe, but it's not a guitar)
