I just threw on a fresh set of Rotosound 66's(45-65-80-105-130) on my 5 string MIM Jazz and the B string is terrible sounding! Anyone else have this problem? Bad string? Just a MIM Fender thing? One thing I noticed with the Roto's was the B string didn't taper before the tuning peg. With other strings, it tapers just after the nut. My last set was GHS Boomers and I thought the B was kinda weak, but now it's almost unplayable. I'm wondering if it's just a bass quality thing and not a string thing? Otherwise, I LOVE the sound of the E-G!
