So far i really like the 85in the bridge, it's to bassy for me in the neck. Not sure what i like for the neck pickup the 81 okay.
Zakk Wylde "not so much anymore" and Brad Noah "original guitarist of disciple" are my favorite guitarist. they both use 81 in the bridge of their guitars.
I have have 2 les pauls, Epi Midnight les paul with dual 81's and an epi zakk wylde with the passive h4/h4a. I also have a Fadded SG with an 85/81 combo.
I think it's more i don't like ceramic magnet pickups to be honest. I prefer the 85 and the h4a in the bridge of my guitars. IMO the 81 sounds great for a ceramic magnet pickup.
I didn't like the super distortion i had back in the day either.
I watched a you tube video of zakk wylde and Slash playing, Zakk's sound was huge, and slashes sound was weak in comparison!
The active EMG's different i think this is due to pushing around more bass.
