Swapped out a hum-cancelling
Dimarzio "single" coil, the HS-3, for a Fast Track1 and am really, really pleased with the results. Out of all of my Dimarzio-equipped guitars, this set takes the least amount of dial in time to get a good sound, either through a tube amp or an Eleven Rack. They really sound good through most patches.
The
Fast Track has a more balanced output with the Gravity Storms and there isn't a large drop in volume that i had with the HS3.
I have two other non-Ibby guitars with what I consider to be great pickups, a PRS with ReWind Creme Brûlée's and a Thinline Telecaster with Kent Armstrong hot P90's. The Gravity Storms, in a mahogany bodied S5470 are easier to dial in than all of them. It's almost hard to make them sound bad!
