I discussed this previously with Rob during our habitual border skirmishes. I missed the bolt-on plate then, that is a dead giveaway, good eyes Jake! This bass certainly contains original Gibson parts and is Gibson-inspired, but it is not a Gibson prototype. At best, something a Gibson worker with access to all these parts attempted thought it is a bit sloppy for that. But mixing a 60ies bridge with 70ies pups and varicontrol on a late 70ies/early 80ies body is weird.
