I'm thinking of buying a bass guitar, I've been playing guitar for about 10 years now and just want to expand a little. I'm looking for a good solid bass. What kind of quality is a used Yamaha Attitude Standard with the p/j pickups and 3 way strat switch and what should I be paying for one? The one I saw is black and in excellant condition. Any suggestions for blues/classic rock rigs in the under 500$ range are appreciated. Thanks!
