Was given the bass. Love that vintage, no high end sound,, but it kept cutting out. Took the back cover off and noticed that the wire coming from the bridge was broken. So ...I see it is soldered to the one pot. *But * my question is this. Does a wire need to be run to *every part* of the 3point bridge(every anchor point) and the strap button/tail piece as well ? And how does the routing go? I took the anchors out(took work as they were epoxied in. Badly) and noticed that only one of the anchors had wire on it. Is this right? Help? Thank you
