I had noiseless Kent Armstrong/Sky P-100's that I didn't care for. They came stock on my Ibanez Talman.They were loud, clear and hard sounding and completely lacked P-90 charm. I now have a Duncan Custom P-90 in the bridge and a Fralin Blues 90 in the neck of that guitar. I really don't notice the hum and interference as much with a P-90 as a tele or strat?
Had good results with the Dimarzio Deluxe 90s, but I think they only offer the Virtual 90s now. Can't be a bad place to start. The Duncan noiseless P90s are pretty good too.
