It seems there are a few TBers who own and play both five and six string basses. I'm curious why that is. Once you have the range of a six at your disposal, why go back to a five? I currently play a five-string electric, and although I have studied upright, my electric bass skills come more from playing guitar for 16 years. Lately I've been thinking, why five? Why not six? Anthony Jackson is adamant that he has never played a five-string bass.
