I would doubt it - you could pop off your guard and check but I would bet as much cash as I could muster that it isn't.
For Music Man basses I think if you want a two pick-up model, buy them that way. Its hard to get the correct pickup and components after market (as EBMM doesn't sell them like that) and you will be destroying your basses re-sale value.
ime, imho, ymmv etc.
