The circuitry of the Gibson Victory bass was the work of Gibson R&D team member Tim Shaw. Electrical components on the Gibson Victory Artist are accessible by removing the pickguard. See also the Victory Artist wiring photos.
There were two versions of the Gibson Victory Artist circuit. The first was used perhaps only in early-mid 1981. This is characterised by having the active/passive switch mounted on the scratchplate. The second is far more common and was labelled Revision B or Rev B on the circuit board itself. It has this switch soldered to the board, and three extra capacitors, affecting biasing within the circuit. The end result is a slight reduction in the high end bite when the treble is full on.
The Schematics are shown below. Click to enlarge (enlarged copy is in pdf format, for easy printing). Thanks to Kirkwood Rough for the creation of these schematics.
