I play a Lakland 55-02 which I must say kicks arse. But there's one thing that bothers me about this bass. My B string doesn't sustain like it should. The only problem I can think of is the string is not a taper core. I bought it with the strings that are on it, so I don't know if this is the problem. Does anyone know if not having taper core strings will affect the sustain? Are taper core strings a requirement for Laklands? Laklands are renowned for the tightness of the B string so this shouldn't be a problem. P.S. I string through body.
