Hey mmmguitar, would you mind elaborating a little more about the Air Norton in the bridge vs. Al DiMeola bridge?
If you want more aggressive mids, I’d suggest de-airing or going full Norton like you were thinking. The ADM is voiced differently from the AN; and my endorsement was to do with feeling the ADM was a better fit for a particular guitar (a Strandberg) than the AN was. The AN emphasized the mids in a way that I enjoyed in other guitars, but didn’t fit so well in that one. The ADM smoothed it out and added body in a way I preferred.
In my meager opinion, I rate ADM bridge>Breed neck>Air Zone>Tone Zone as similarly voiced pickups from lowest output to hottest, according to one’s needs (e.g., if you want more output out of a PAF Pro, try the Breed Neck. If you want a warmer vintage-output PAF but don’t want to get into hotrod territory in terms of output, the ADM may be worth trying backed off from the strings a bit. Etc.).
As far as de-airing goes, I may try and first go the half-air way, since it's merely a nuance in the high-mids, that I think I miss.
I had a Norton in a very similar guitar (a EBMM Albert Lee) and remember it being too far away from the Custom DiMarzio in my (Super) Sports.
Plus, I like, that the AN is significantly quieter. Whereas the Norton is in EBMM Custom Dimarzio territory.
For example, with my SLO Clone increase the lead channel's gain from 3-ish (EBMM DiMarzio) to 4..4.5-ish (AN) to achieve similar gain levels.
Also I like the AN's punch or push, actually I was expecting it to be more "spongy" or saggy, which was my experience with the AT-1, compared to the Custom Dimarzio. With the AT-1 I thought it's the Airbucker technology.
As I am writing this, it might be, that for me the AN could just have a little more bite or presence.
So, as far as the ADM is concerned, would you say it's overall feel is warmer in the hi-mids than the AN ? Which would lead me to the conclusion, that the ADM might be the wrong pickup for me.
