I'm a believer. I mostly play this guitar through a reissue deluxe reverb or '63 princeton. The '65 set me on a quest which ended with a set of Lindy Fralin Vintage Hots. They're in another guitar and they're the best I've heard. These are great pickups for the money though.
Tone is well-balanced, open, throaty, and very responsive to pick attack.
Full bass response, and the treble end is typical for a Vintage type Strat pickup, but not harsh. My guitar has a solid mahogany body, maple neck, and rosewood board. The mahogany body is not typical for a Strat, for sure, but these seem to work. There is enough low end and high end response from these pickups to balance the midrange emphasis of the mahogany body. So, it is important to match pickups and guitar woods to get the tone you are after, I feel.
