I think everyone here is at least partly right.
Yes, there are closed-minded musicians who won't hire anything other than a four-string player. If you're a four-string player, or don't mind using a four-string for those gigs, then great. If you're not either of those, there's nothing wrong with not playing for them.
If you feel you need more than four, also cool. I personally like having more than four strings and I only have one 26"-scale four string... but if I got a gig I would like to play which *required* me to get a four-string, I would have no problems buying it. Given an option, I would play my six though.
And there are situations where I've been sought out to play my eight-string: I run it into a wet setup EQ'ed to the mid-high frequencies to play guitar chords and lines, which some people like.
So it's all cool.

Exactly!
