The legendary Bass Of Doom, nicknamed by Jaco himself, is a 1962 Fender jazz bass that Jaco removed the frets from and refinished the neck with boat epoxy. This customized bass was the only fretless instrument Jaco ever recorded with throughout his career right up until it was stolen from a Manhattan park bench in 1986. Despite repeated attempts from friends and family to locate it, the whereabouts of the famous bass remained unknown until it showed up in early 2006 in a small guitar shop on New York’s West Side. Unfortunately the owner of the shop refused to return it to the Pastorius family resulting in protracted legal squabbles. Almost two years passed before Robert was able to jump in and help make it possible for the family to settle out the case and regain control of their father’s prized bass. When asked about his getting involved, Robert commented, «I felt a strong sense that it was the right thing to do for Jaco, and the family, whatever it took.»
