Hola, I am in the middle of a significant GAS attack and I am wanted to get all kind of basses really. I currently own an Ibanez Artcore which I like very much, and an Ibanez GSR 200, which is okay. The Artcore, is not a rock bass, and want a better bass the the GSR 200. Currently I am think about picking up a Musicman S.U.B. I do not know if I want to go 4 or 5 string though. Four strings has not been particularly limiting to me yet, but all the same, I do not have a 5er at all. Care to lend me some feed back on the pros and conds of the 4 and 5 Musicman S.U.B.s?
