If he didn't get himself killed in a barfight... I know he used his Jazz, and I've seen instructional videos where he was using something "Alembic-like" but I can't remember what it was. I remember reading that his amp was an Acousitc with a reverse-ported 18" or something like that. Someone please correct me if I'm wrong. --- If he were alive today, what would he play for bass and rig? I have two ideas: 1) Whatever junk he could beg, borrow, steal, abuse or destroy. Back in '86, I used to take bass lessons in New Jersey from a fusion guitarist who gigged regularly in NYC. He had NO LOVE for Jaco, and nothing but horror stories: Jaco passing out in the back of someone's car... borrowing amps and cranking everythng up to 11 and destroying the amp... borrowing basses and doing crude carvings in them with a screwdriver (true story. Where's that bass now?). So my first guess is, he'd play whatever someone handed him, and destroy it on the spot. 2) Some "signature edition". He would have miraculosly cleaned up his act in the 90's and struck a deal with a famous maker (not necessarily Fender) and designed a signature edition that he felt "beholden" to play. (Warwick? Ibanez? Lakland? Mike Lull?) --- I have no idea what kind of rig this "theoretical jaco" would play today. Boogie? some Ampeg "Jaco Signature Series"? Sunn? Would Acoustic have been bought and re-distributed? Any wild speculation? Would he still be playing 4s? or would he be a 11-string tapping monster by now?
