I searched the FAQ and newbie links, but I can't seem to find anything about this. Whats the big advantage of a 5 string? Obviously you have the extra low-B string, so you have another string to make noise with, but how usefull is it? Most bass players (including professionals) seem to do fine with just their normal 4 strings, so I'm guessing there might be more to it. So why go for a 5th string?
