1993 2020 bass
This is a somewhat rare bass. It is based on the 3001 body shape. It has the same neck and electronics as the 4004 bass. The neck and bridge are the same as the 4004 bass. The serial number is on the neck plate and on the jack plate. The pickups are pretty much the same as the 4004 humbuckers, except the height is controlled by rear loaded allen screws. I think it originally had a black truss rod cover / nameplate.
