Hi, my bass came with a couple junky no-name stock pickups, so based on the dimensions and specs, I ordered a new Dimarzio "Model J" (DP147) bridge pickup and a "Will Power" (DP145) neck pickup

. The wiring seems pretty straight-forward, just questioning the phasing thing...
Does anyone know off-hand if this combo will require reversing phase on one of them (i.e., switching the red and green wire), or is this something you never really know if it's necessary until you try??
Thanks in advance!
