I have 47 years of guitar, a few of dobro & lap steel, but I am just getting interested in bass. I play blues, swing, r&b, light jazz, 50's country and early rock. I play a lot of bass lines on guitar and often wish for a low B string. So I am thinking I would eventually gravitate to a 5 string. Would it be best to start with a 4 string for a year or two and then make the decision, or would starting with a 5 be ok? I guess the question comes down to, if I started with a 5 string would I be inhibiting my learning progress. I put this in the instruction section because I am hoping for a few more thoughtful responses, than the stereotypical poll of "what's better 4 or 5" which belongs in the bass section.
