The guitar, bass guitar, and it's strings were and are designed to be tuned to "A=440". It wouldn't sound "right" when you tune it either flat or sharp...they're either too "floppy" or too "tight"! As long as I have played with an ensemble, the "horns" have ALWAYS transposed to the guitar.
Can anyone imagine a "jam" with other guitar players where everyone is in standard tuning, and that one guy playing on a "capo'ed" "I fret"?
