What happens when you play at a jam with that guitar? I'd think that you'd just have to tell everyone else what key you're in etc. Does the Bass player necessarily have to tune his bass to Eb also?

If the bass player can’t play in whatever key you call out (Eb or any other) then he has no business playing at a jam.
He’s got every note there on the fretboard he needs.

I don't remember jimi worrying too much about being in tune either though.

ha! yeah, that was a secondary consideration in those days ... when i first heard Dylan's "Highway 61" album, i wondered if they were doing some exotic mideastern 12-tone tuning (the raga-rock era, you know). i ultimately realized they were just too stoned to get in tune!

WARNING – name dropping about to happen.

I once asked Jorma what he and the band did before there were cheap portable tuners and strobe tuners and so forth.

He said “No problem. It was easy.”

“Easy?” I asked. “How?”

“We’d just play out of tune!”
