Hi, I am a full time stage/studio musician. I have been playing guitar, banjo, and mandolin for many years, but am hoping to add my 1st bass to my toolbox. I think I have decided to go a more classic/vintage vibe route. I had previously considered the possibility of getting a longer scale (35' plus) 5/6 string bass...figuring it could cover some serious territory and work in any situation. I think, for now, I am going to start with something a bit more traditional. I am thinking about a 5 string Jazz Bass or 5 string P Bass. I want to get something decent quality, american made, and will probably upgrade the electronics down the line... Can anybody tell me more about the differences between a P and a J? It seems like the 5 string versions are not popular...why? Thanks!!!
