I checked into it more from the original owner. Your right, bridge pickup could have been replaced in the late 70's. I'm not a Rick expert by any means on the technical details and appreciate the help.
Price reduction to consider this. $3800 shipped.
Bass does play and sound amazing. Best Rick I have heard.
