On all instruments that I play during any given gig, my rule of thumb is "whatever suits the song".
We do a lot of covers, and maybe 20% original songs, but I do like to try and make things sound like the original recording (or radio hits) as much as possible.
Drums? Digital drums make it easy to dial in a kit with the right tones and tibres.
I literally spent days one time, hunting down the right cowbell for a key section of a Steeler's Wheel song,
Stuck In The Middle With You.
Guitar, I'll use a Fender for certain songs, and a Gibson for others, just to get it right.
Just the proper amount of distortion or palm muting, to make it spot on correct.
Bass is maybe even more important.
A lot of songs require picking, others the fingers, and yet others still some combination of pick, thumb, and fingers.
Old people high school reunions are real money makers, more so than bar gigs or open air sports festivals.
I love to bring them songs that sound like we just dropped the needle on that old album on the turntable.
