I'm planning on installing Carvin pickups for my next bass (6 string). I would like to put a H50N humbucker in the bridge position, and a J99 in the neck. The J99 has an option for reverse winding to cancel hum - I'm assuming this is used in conjunction with another J99 pickup. Would there be any hum/grounding/etc problems using these two pickups in this manner? H50N + normal wound J99? If i substitute the H50N bridge pickup for a J99 (2 single coil pickups), would I need the 'reverse' wound version, and where would it go (neck/bridge)? thanks..
