I was visiting a local music store and they had this used hot-rodded P-bass for sale, eh? So I asked them what was the story behind it and they said the previous owner bought it but wanted a pure Precision sound so after only a few months, he sold it back and bought a Precision. Question: Why would someone want to sell a Hot-rodded Precision and buy a Precision? When I played it, it sounded exactly like a Precision, except that you could add a Jazz bridge tone (and the annoying hum), if you wanted. But you could turn off that pickup. Why? It seems like an upgraded Precision? Can anyone offer insight?
