I know there are many reviews here but this pup deserves yet another. I have this pickup in an RG and in my Gibson Explorer. I love how fat and smooth this pickup is. I play classic metal, rock, blues, instrumental, and the pup does each well. One of the coolest things about the pickup is how well it splits into single coil mode. I get close to a strat sound from my Gibson making it very versitile.
I liked the split so much that I split the 36th Ann Paf in the neck of my Gibson V. I did not get the same results. The volume drop on the 36th Paf is way to much and the tone is nowhere near as good as the Air Norton's split sound. I'm considering putting an Air Norton in the neck of the V as well.
Air Norton gets a great high gain lead tone or Fat old school Gibson tones. Can't say enough about the pup; if you like smooth, fat, and sweet, it's a great pup, split it and get a great single coil tone as well.
