The Mag is 14k coil, A5 poles, no stagger. StagMag is 16k coil, A2 poles, staggered. My StagMag sounds like a Distortion with coils in series (but with a bit of Brobucker/PAF mid-chime, which I think is coming from the A2 poles), a Telecaster with coils in parallel, and Strat with coils split. Very useful.
Here's a review:
