I've heard bassists complain about the keyboard players and their left hands. I've never ran into this being a problem. Not saying that it doesn't happen but I've never really found it to be a problem. One band I'm in has keys and another has two keys. Then there is a third band without keys that I find myself wishing there were keys. Go figure.
The first band is southern rock, the second is a art rock type of thing and the third keyless is old style country.
Either way I like having keys in the mix, it really opens a lot avenues to explore.
I wonder if the bassists for some of the bands like the Allmans, Billy Joel, Elton, PFUNK, NRBQ, Roxy Music ,10cc or Wilco ever had problems. Hell Skynyrd actually stepped up their game incorporating Billy Powell.
