In my opinion, Fender basses are among the best sounding, highest quality instruments known to man and are without dought some of the most widely played basses in the world. Both instruments are tonally versitle as well as musically(genre). The P-Bass has a very comfortable feel, clean punchy growl, and thick neck. The Jazz has many tones, bright, warm, and punchy where it needs it, and the thinner neck is pretty comfortable. Both have a nice weight and unique look to them. I'm curious as to which is better? Which bass to players like better and why?
