These are my first active pickups. I generally disliked active pickups until now, but these are something else, they sound like regular PAFs and someone told me they are passive ones, I would believe it so. The bridge is powerful and the neck is articulate and not bassy as many neck pickups are. The signal is strong, there is literary no noise or hum so they are perfect for studio recording. They have 2 additional voices, hot rodded which is great for dirtier sound and a split coil tele sound. Now in split coil there is almost no loss of signal output strength. Both voices are activated via two pull/push pots. On my passive ones splitting used to lower the signal strength in half...not with this ones! I've put these in my Schecter S-1 Elite Diamond series guitar. I have it done by a professional, not by myself and I was informed it was easy job to do. The pickups require for you to change all of the electronics in guitar with the one you get in box, since this architecture of pickups require 250K push/pull pots. Highly recommended!
