Usually known as "Boner" Jazz Basses, these early American Standard models (designed by George Blanda, who was Fender's senior R&D engineer during that period) were discontinued in 1994 and shouldn't be confused with the Fender Jazz Bass Plus, which has the same 22-fret neck design, but utilizes a different (downsized) body styling, Lace Sensor pickups, Schaller "Elite" fine-tuner bridge on the four-string model or Gotoh Hardware high-mass bridge on the 5-string model, and Phil Kubicki-designed active electronics. Unlike the Fender Precision Bass Plus, which had an optional maple neck, the Boner Jazz Bass was offered only with a rosewood fingerboard.
