I am presently doing a restoration project on an old early 70's japanese import bass. I am going to use Bartolini Rick replacement pickups and need some help.... I've filled in the cavity where the old pickup was, and now need to route cavities for the new pickups, and I want to put them in approximately the same place that Rickenbacker puts their pickups. Could a Rick owner please take some measurements for me? I need a measurement from the edge of the bridge - not the saddles - to the edge of each pickup that is closest to the bridge. Thanks! ***Should this be in pickups??
