Seeing how this thread is about 21 years overdue, I figured I'd start one.
Fender started this line in 1989 and it ran until approx. 1994. There were four models:
The Jazz Bass Plus IV and V:
The Precision Bass Plus (AKA "Longhorn" or "Boner") as seen in the middle here: (these three are my current lineup):
The later version of the Precision Plus (thanks for munjibunga for the pic):
All models had stock Lace Sensor pickups. The jazz models and later model of the precision also had a Kubicki designed pre-amp with bass/treb knobs. The Jazz had an extra rotary switch that allowed you to play passive, active or active with an adjustable mid boost. A 4th position turned the bass off.
The Precision Plus was the first bass made in the Corona plant.
The jazz V preceeded the IV and was the first truely active bass that Fender produced.
My review of the Jazz Plus can be found
