Currently I am using my friends Squier Affinity P-bass, and have been for some time now. I started looking into Music Man's because I felt that I needed some more tone shaping abilities with my bass. However I jammed with a couple of friends of mine and it sounded perfect, sat right in the mix and got the tone I wanted with it. Even with my little 75 watts 1x10 combo it managed to fill the room without losing tone. It seems every time I doubt the P-bass it proves to be the bass that I really need. Anyone else thought that they needed to upgrade to a premium, on board pre-amp, super amazing hand crafted bass when all they really needed was a affordable, passive one?
