Re: DiMarzio Breed Vs. AT-1
What don't you like about the Tone Zone? Technically, it's also a "hot A5" pickup, after all
Some people have had really good luck modifying the Tone Zone, so that's a possibility, depending on what you want from it.
I hear only great things about the Gravity Storm set. I almost bought a set myself recently as I was also looking to move away from the Tone Zone/Air Norton combo in one of my guitars, but I ultimately settled on the Transition set, which, despite being ceramic-based on paper, is surprisingly dynamic and responds much more like an Alnico pickup set. BuddRoyce, the DiMarzio forum administrator, gave his review of both the Gravity Storm and Transition pickups a while back and came to the conclusion that both sets were some of DiMarzio's best, but the Transitions were his pick for overall versatility. Food for thought.
I will say that the AT-1 sounds incredible in my Jackson Rhoads with 500K pots. It's a guitar that has proven to be particularly picky about pickups. If pickups were thick enough to tame its piercing top end, then they often weren't tight enough or they lacked the harmonic qualities I like under gain. If they were tight enough, they were either overly hot or too harsh through the upper registers. The JB was actually decent in this guitar and the Black Winter was close to perfect, if not a little snappy and bright, but the AT-1 is the perfect middle ground in this case. It's juicy, tight, dynamic and a real rocker from top to bottom. Nice note separation and a smooth treble response with a dose of attitude when you dig in. Plus, really musical sounding harmonics for days. It's a keeper in that guitar for sure.
