I have a set of Lane Poor j-style pickups in my bass, but their casings have cracked (I think due to too much pressure from the springs under them combined with heat from a couple of road-trip gigs). Does anyone know of any way I could get the guts put into new casings. It doesn't look easy, as they are totally sealed and epoxied in. They sound great, and work fine, other than not really being able to adjust their height anymore. I just want to salvage what I can. Help me save an endangered species. Thanks in advance.
