I've been a guitar player for 50 years as of this month. Due to arthritis setting in; I have had to all but retire the 6 stringers. I started taking up bass more seriously about 2 years ago, when I saw this coming on. The string spacing, ect. made it easier to play than a 6er. I first bought a Hofner CT, and then a Ric 4003, and now a 62RI Jazz bass. I really want a 62RI precision, and was wondering what your opinions were on the difference in the Jazz, and the Precision as far as the necks, and also the tones. I will be playing mostly Motown, and almost all 50's, 60's, and 70's music. I have gravitated towards the Jazz bass among all the ones I currently own, and am just wondering if there's enough difference in the J and the P to make it worth owning them both? Thanks in advance.
