After watching this build diary you got me keen to build a customised MMB-4 and I'd definitely put the 2nd humbucker in.
I'm also keen to hear how you think the positioning of the neck pup is and the difference in sound from the bridge pup. The pickguard allows a fair bit of movement for the neck pup
