I've got a 2012 Am Special tele with the older Highway 1 Texas Tele pickups, and have been thinking about adding a middle pickup like in the style of a Nashville. I love the current pickups just as they are, and don't want to swap them out. These pickups are higher output then "normal" I am looking for some guidance into how to find a pickup that will match up with these. I've seen specs in the neighborhood of Neck: 9.77k, Bridge 16.27k. Though I can't seem to find where I read it, I remember seeing that they are Alnico 5, N/CCW. I like the sound of Alnico II, but its not a dealbreaker. I assume that since the pickups are N/CCW, I want to find one that is S/CW in order to get the hum-cancelling, out-of-phase, strat thing. My questions are: Is it safe to assume that the output, wind, and polarity of my pickups are going to be the same or "close enough" to the specs found via research? What output do I want to look for in a middle pickup to fit in with my current pickups? (I realize this is subjective, and am open to either advise or "conventional wisdom") Are there any pitfalls to putting an Alnico 2 pickup with two alnico 5's that I should consider?
