** (just some playful teasing here) **
IMHO I don't understand why any bass player would exempt a five string from their arsenal. If I had to have only one bass it would be a fiver. There are just times when the proverbial "brown note" is required!
I'm not ruling out the possibility of a four string in BEAD one day though.
Also, those of you who play four strings but tuned WAY down; I guess you get the best of both worlds! LOL
(OK, feel free to flame me if you wish. I can take it.

Just stirring the pot; shaking the tree so to speak.)
