After re-reading the intial post I can agree that P90s deserve a second look. Certainly have a very versatile range. They react to the volume and tone controlls more than a HB imho, giving an immense range from sing to scream with a signature open and growly midrange. Very warm and natural. They let the guitar come through a lot too. The bottom end has a certain clear, natural quality about it and the top end it extended compared to a HB as it is essentially a SC.
Currently running my MQ neck with a SH middle and Crawler bridge and it is wonderful. The MQ feels good from clean, to Sweet Child o Mine, to Petruccie´s Glassgow Kiss, but does each in its way.
And the Manhattan neck in my semihollow is the sweetest, most natural thing I have ever heard in a PU. Plus it gives me my favorite vintage fuzz sound by a mile.
