Re: Magnet way too narrow in new Dimarzio D-Activator??
IDK, I own a set of those pickups, and the neck pickups is certainly not low output, although it has a lot of its energy focused in the highs and upper-upper mids which may make it seem like it is a little cooler than it is, its still almost as hot as some of their highest output bridge models, The hex stud poles are actually thicker throughout than the typical cap hex, which are just thicker at the head, but thinner in the threaded, and they don't protrude from the base plate, which really directs focus. I definitely wouldn't call it a pickup with lack of definition either.
I honestly think it might be the case of a missing spacer just like the picture I posted shows. I have a suspicion that Dimarzio might build pickups more on an assembly line fashion, since they are a high production company, where in somebody makes a bunch of preassembled magnet and base assemblies, and its possible somebody grabbed a baseplate intended for an air model. Mistakes happen, and even some Duncan products have shipped with errors as well that make it to the sales floor, such as unintended reverse wiring of the conductor cable, that cause phase issues with other pickups. That happened to a forum member just recently.
I do agree that you should take up your beef with Dimarzio's customer service instead of forum members here, as it's their product you have issues with, not anyone's at this forum. They are both better equipped and more obligated to thoroughly answer your questions regarding their products and why yours is the way it is. They should be able to make things right for you. I have delt with hteir customer service team many times, and they have always been more than willing to help.
