but, I am very dissapointed in the P-rails I installed a couple of months ago. Yeah, it sounds ok I guess, but there is so little difference between the three options that I hava a hard time telling them apart other than on a clean setting with no effects. And the noise! sheesh. Trust me when I say it is wired and grounded correctly, I even went back and re-grounded everything twice, but to no avail. The P90 sound is the better of the three, but honestly doesn't stand up to the miriad different PUP's I have in my other guitars, Dimarzio or Duncans (I have sixteen different ones) I have a set of the SH4-SH2 humbuckers and they sound fantastic along with various Duncan twin rail singles that all sound great, and no noise unless I tap them, and even then way less than the P-Rails. I did my best to like it, but it will be on the 'bay shortly. Hope I didn't offend anyone.
