Please forgive me if this is a really silly question. But I've never modified a bass before. I got a cheapy MIM Active Jazz 5. And I got a set of NJ5F's. But... I didn't pay attention when I ordered them. They do not come with the plastic covers, as they are supposed to fit inside the standard covers. But... the covers on my Jazz are single pole covers. These pickups fit inside the covers... but they don't fit the holes. Where can I get a set of covers with two pole holes per string??? I've found some for 4string Jazz's.. but not 5 string jazzs. For what it's worth... even with the mismatched covers... the new pup's sound GREAT in this cheapy bass.
