how to get a tone like joe pass

he has a very very specific sound and i was wondering if anyone knows what eq/amp/effects and guitar settings he used.

edit: i meant the tone that sounded basically unplugged, maybe it was, when i play my guitar unplugged it sounds almost exactly like his tone, but when i plug it in alot of that "hollow bodiness" gets lost. like alot of people said archtop straight into pa might just work well, thank you.
