After having played for the last six months or so on a $150 Yamaha with a slightly warped neck (given to me free by a friend), I finally have enough money to make a significant upgrade. With $500-700 to blow (probably closer to $500), what basses would you recommend looking into? I've been messing around at GC for the last couple days, and I could probably afford a Mexican-made Fender or something, though I'm not sure if that is the best direction to take. What do you guys think? I listen to (and would like to be able to play) a wide variety of music, by the way. Everything from Eric Clapton and Yes to Rush to Rancid to the Chili Peppers. Thanks for the help.
