I'm new to the list, and started playing bass again with a jazz group after a few years of not playing. Last time I was playing with a group, it looked like the 5-string was going to be the instrument of the future. Now I'm not so sure. There are definately more of the around, but there are alot of 4-strings still being made. I'm happy with my 4, but sometimes the extended range would make life easier. I was thinking about getting a 5 but adding a high C rather than the low B to facilitate playing chords. So, what's the general feeling among bass players? Is the 4 still most mainstream? Do people see much use for the low B, or is the high C more useful?
