I went to Sam Ash to tryout a few Fender jazzes and I have concluded jazz basses are not for me. The big round P bass sound is a sound I have grown to love since picking up bass. It's naturally fat and boomy and can be as big or small as you like via 1 tone knob. You can take the fat and boomy out by playing in a different position with the tone knob all the way on and 500k pots would help. You cannot however, get a P-bass sound out of a jazz bass unless it is active. The only 2 basses that could mimic P-bass fatness were the marcus miller, and the ibanez roadgear setup. Not to say that a P bass can perfectly mimic a jazz but... Precisions are definitely my sound.
