I had a 78...weighed as much as a boat anchor...it was also one of the worst, most lifeless basses I've ever played

Opposite experience with my 75 Jazz, which is a proper boat anchor (5.5kg!), but is the most resonant, lively-sounding Jazz Bass I've played...Seriously hit or miss period for wood quality, as many others will surely attest!
Mine came with microphonic pickups which, by the sound of it, is the case with the one you've tried. Sounded great when I tried it out (and subsequently bought it!), but squealed like a banshee through a loud amp before I'd even added any additional gain...Stuck some Bare Knuckle PE pickups in it, and now it's just perfect! I'd never sell it.
