So I read on here awhile back that there were certain years of MIM jazz basses that were made with different woods (poplar?) and didn't sound or hold up as great as some others. What should I know about the MIM jazzes BEFORE I buy sight unseen (off ebay, for instance). Someone once told me to stay away from the ones with strat style knobs. Is that a sign of the "bad" ones? What's a good year? Someone else said '98 was a good year.
