Over the years, my opinion of certain pickups has changed quite a bit. Some pickups like the Air Zone, I have always gotten along with in many guitars. Some that I initially disliked in one guitar, like the Norton bridge, became a favorite when I installed it in a PRS Singlecut. The 36th Anniversary went from bland to amazing when I put them in a Les Paul where they belong. I also found the Breed bridge boring until I put it in a Jackson DK2M. Some that I began playing years ago like the Duncan JB and Jazz are my least favorites now. Every time I retry them, I like them for a few days and then they start getting on my nerves again. Some like the Cruiser single coil I had to learn how to use, and now I love it. I left some, like the Duncan 59, behind long ago thinking I could find something better for an SG Standard only to return full circle and wonder why I wanted anything else.
What pickups have you liked or disliked only to change your mind later?
