I'm listening to the radio. Bob Marley's "Three Little Birds" came on and I was reminded that every time I hear this song the bass guitar, on the lowest note of the backing lick (or whatever you would call it) always sounds, to my ear, ever so slightly sharp.
I've noticed this before on other songs, too. I've always imagined that it's probably inaccuracies on a fretless bass, but have not found anyone else mentioning it, so I assume it must be me.
Is this a common phenomenon - where very low notes are not accurately heard?
