This is an absolutely wonderful four-string fretless bass specifically designed (in 1989) by Joe Zon in collaboration with bassist Michael Manring, whose work often uses unusual tunings. Not only does the organic design and deep cut-away make for extended reach of the graphite neck (three octaves!), but the wonderfully figured wood readily seduces the eye. Quick tuning and re-tuning is facilitated by four Hipshot keys and two bridge levers that raise or lower all four saddles or can be assigned to a single saddle. Along with the Bartolini pickup, there are four Fishman transducers mounted inside the instrument, in both neck and body. Talk about sound and fury!
