I havn't tried the AC in the neck position. Give me a couple weeks, though, and I will have tried the AC in the neck of a LP. I can say that in the bridge position it is warmer, and more dynamic, and more touch sensitive than the 36th.
I'd definitely like something quieter and with more touch response and dynamics with the volume/tone controls.
^^This the AC does well, at least in the bridge position
The Bluesbucker is pretty loud for a neck position pickup unless your using a high output pickup in the bridge position. I have a BB in the neck of a superstrat and a TZ in the bridge barely balances it.
I have no experience with the EJ neck.
