Hello, I've got yamaha trbx305 and I really love it's comfy neck and feel, but the problem is that I don't really love it's sound, especially low end isn't punchy but a little muddy. Also, if I play metal, I really love to dig in hard to maintain consistant, ballsy tone, but as soon as I strike lower and lower notes, it gets more and more distorted, (gear : hartke ha3500, hartke transporter 410) and also B string doesn't have any clarity at all. So I was wondering if it's common issue on this basses or not? And also, I think to try to replace onboard preamp with tone monster sbk 3ad(1stacked pot). Will it solve my problem or do I need to upgrade pups as well?
