Thanks for finding that picture... In the '84 guitar player article he states that he gets "lots of free" basses and amps.. but seemed to stick with the fender and the acoustic 360s. I was just surprised when I read the interview with Jaco's son and Hartke and he said as far as he knows he used it exclusively after he gave him the cabs.. I have seen lots of late vid clips and pics but never saw him playing 1.... he would have used it on the DCI video I would have thought... thanks for finding that pic!
