I really like the pickups, plenty of tones to be had. I reversed the neck pickup (as shown in the picture), gives a nice single coil sound that just was possible with the stock pickups coil split. I find the pickups much more vintage sounding than the stock pickups, but it can still do metal/djent stuff with the bridge as a humbucker.
Check out some reviews of the P-Rails on youtube, see if you like the sounds on offer.
