heard they are the best. figure they would really go good with my project bass. i am visiting the site and getting confused. there is alot obout active controls. do the pups need to be active to go with them? how do they work? i do not want them on a j control plate, hoping to make the bass backrouted. the pickup plan is a mm and a neck jazz-like pickup (debating on a traditional jazz style, or nordstrand fat stack/big singles) if it means anything. ok so an audere compatible with passives, and not on a jazz metal plate. what does that narrow my options down to, and what are the differences between them?
