A BUNCH of custom handwound pickups as well as some duncan & gibson production models- all played through various boutique and even some production amps. One of Zhangs custom winds is on it too!
For the gainy stuff, I'm partial to the Aldrich and Rio BBQ-both are thick without harsh highs. For PAF-ish tones, I'm digging the marshallheads for invoking the Angus vibe, and the Pearly gates I think holds up pretty well with many of the handwounds too. Not sure I can pick a fave of the PAF stuff- they ALL sound good.
