I'm currently playing an Ibanez Soundgear 300 DX, but I've been looking around... ...I've seen a MIM Fender Jazz bass online for a decent price at a few sites, and I think I may be able to get $200 for my bass on a trade-in at a local shop... What would you do? I've been playing for around a year now, my budget is tight, and I'm lefty. I don't like the springy sound of the mid's and treble on my bass, I like the sound of someone like, John Paul Jones. Sooo, if I get around to trying one out, should I make the switch?
