Hello, I was wondering if anyone out there could tell me when the first Pbody basses with a P neck pickup and jazz bridge pickup originated and what color schemes they came in (Tobacco Sunburst with gold anodized pickguard, etc.) Did they go all the way back to the 50's or did they start in the 60's or 70's? I've seen these basses called precision specials and even precision deluxes (I think). Any pics would be appreciated. Thanks.
