kh-emg's?? thats just a set like the emg-zw, kirk hammet emg's, zakk wylde emg's, there both just sets. The EMG-KH' come with two 81's, or you can get the other set with 81 in the bridge and two EMG S's in the middle and neck. i dont know how you can get the best 'tone" from a set, ussually you judge it on the pickup. But like i was saying the 81's are the best emg's for the bridge hands down and i would never think of putting one in the neck like one of the kh sets.
