For me, the most beautiful guitar ever made is probably the Fender Jaguar, as played by Kurt Cobain.
"There is no excellent beauty that hath not some strangeness in the proportion."
But never really wanted one as it's a very... backup, rhythm styled guitar and I am a natural shredder virtuoso, high speed solos on the 24th fret.
But for twanging away basic simple backup music and nothing more this would probably be it.
