Lordathestrings: The 'catch' is, that because it is so touch-sensitive, you need to be very consistent and controlled in your playing, or the results become unpredictable, and you may find yourself fighting to control the gain-generated overtones.
I'm curious, are EMG's anything like that? I've been thinking of EMG 81s in my jackson to get the kind of james hetfield-ish crunch. The thing is, now lordathestrings' comment made me wonder: how hard are EMG 81s and 85s to control?
Thanks
