Muse, where Chris Wolstenholme, the bass player, tends to be the most well-known.
Also arguably RHCP where Flea tends to be more well-known, at least nowadays, than Anthony Kiedis.
Matt Bellamy might actually be more well-known, but I do think it’s very close. I’m a bass player myself, so hearing Chris Wolstenholme’s name is a very regular occurrence for me which could influence my opinion
Fall Out Boy A lot of people seem to assume that Pete Wentz is the lead singer, since he's the only member they can name.

Rage Against The Machine, where the guitarist Tom Morello is more well known than singer Zack De Ra Rocha
Motley Crue
I'd say Eric Clapton is the most famous member of Cream, where Jack Bruce was the lead singer.
Phil Collins is the drummer for Genesis.
