If you really want the best PAF type pickups, sweet, full, harmonic. Its hard to beat the Duncan EVH (evenly voiced harmonic). It is modeled directly after EVH's pickup from the first albums (Im assuming your an EVH guy). It is very expensive. Its from the custom shop and is the only Duncan I like. Its really just a strict PAF clone wound a bit hotter. You dont have to be into EVH to love this pickup. Hell all it is is a great, full sounding PAF.
This pickup makes such a huge difference most people would probably crap themselves. Most people cant get past the price or the association with EVH though.
