Hi. Ive just bought a PRS Swamp Ash Special. It has P90's fitted but there not particularly nice sounding ones! As I love the sound of the mini-humbuckers on my old Gibo deluxe, I have decided to put a Mississippi Queen in the bridge. My problem is, do I instal a second one in the neck, or shall I put a Mule in there? Any other suggestions would be apprieciated! I just want it to be a tone machine! Thanks.
