My experience with it over the years is that it is nothing like a single coil and 100% just a low wind humbucker tone. The duncan full shred neck does a better job at what dimarzio describes, especially with the pole piece mod I posted in the mod forum.
Wish that wasn't true, because I'm generally a dimarzio guy and I can get them in more colors and cheaper. Sadly, this pickup just does not cut it as a bright/tight single coilish humbucker, there are better options.
The ultimate, though it only comes covered, is the fralin twangbucker. Wound to 9k turns in the neck position it has enough power to play nicely with a bridge humbucker, and it is bright and tight in the way the hfh claims, but sadly, is not. Tracks fast playing like a champ. Can still sound 'traditional' with a .0022uf tone control rolled back as well.
