First post, yay! Anyways, after a long break I am finally getting back to working on the prototype of my first bass. Last time I worked on it I ran into a bit of a snag with figuring out how to make the pickup cavities. In my research, I cannot seem to find how the depth is determined, as well as the easiest or cleanest way to make the cavities for the pickups. Any and all help is appreciated! The pickups I am using are a set of Delano JSBC5 HE 5 String Skinny Soapbars with split coils.
