A lot of this comes down to rock showmanship compromising your playing though, right? I wouldn't know Pete Wentz if he passed me in the street & couldn't name one of his songs but bands like his are often about an image (& I don't necessarily just mean how they look). I wouldn't expect him to release a tuition DVD called "Advanced Harmonics on Unusual Frets". Fair play to him. He has his own sig bass too (nobody mention Avril!)
A few challenges to some of the bassists under fire here. I worked with a bass playing producer back in the 90s who raved about the U2 bassist. I'm not a fan of the band personally but would they have been as popular with a different player? He does what he does & it works.
Gene Simmons (& that YouTube video seriously undermines my argument but then I've never tried soloing in S&M gear with a dead cat on my head) is actually responsible for some very tasteful playing on a few tracks on the early 70s records - closet Kiss fan so I know they were ones he played on.
Also Bill Wyman, please see the U2 argument.
Oh & Paul Simomon may have been learning on the first record but boy did he get there? His influence answers so many critics. Sid Vicious, see the Pete Wentz argument.
If you want awful bass playing, come & watch me on my upright after the 3 pint mark!
