Another option besides the usual P/J would be a P/DC. Mike Lull has made a few with that comboYeah, I think I'll stick to P/J. I've seen J/MM combinations, but rarely P/MM. I assume there's a reason, but I don't know what it is. About the only ones I found on youtube were Haeussel Jake basses, which sounded good in the demos, and one for a Schecter.
Greg @RocketMusic Demoed a 4-string version here
A year or two ago I tried one myself at Mike's shop and the pickups balance very well.
