BG Pure 90. I've had a ton of P90's from Gibsons made from the '80s-2010s, to Bare Knuckle, Duncan, and Lollar.
The BG's are right up there with any of them. I have one in the bridge of a 61ri SG, and another in a Gibson Adam Jones Std. Bryan is a fantastic guy to deal with, and makes legit amazing pickups for well under the price of much of his competition.
One of my concerns with many HB sized P90's was the chrome or nickle surrounds or covers. According to some it changes the pickups magnetic field, and so also tone. I actively avoided P94's and Phat Cats. I also tend to not like the look. So I looked for an HB sized P90 without any metal aside from the internals and mounting hardware.
