Great thread Mark! I get tired of reading reviews about how great a certain pickup is, when it gives me no idea
why it's so great. The only pickups that I have exchanged for stock pickups are the Gibson Classic 57, and 57 Plus, on an Epiphone LP Standard Plus Top, and I put Lace Sensor Gold Pickups in a MIM SSS Strat.
I prefer a good clean tone as a starting point, and the Classic 57's certainly took away the muddiness that I was hearing in my the Alnico 3 pickups. I now get a broader spectrum of clean tones as a starting point. Of course, playing through the right amp, ensures that those tones come through to an audience. Why the 57's, rather than a Burstbucker? Well, it probably has to do with the sounds that I heard growing up. I prefer a more vintage sound (hey, I'm 58, ok?). It just sounds right to my ear. The Lace Sensor Gold pickups were more of a "I'm game to see the difference" choice, after listening to many videos, and reading many reviews. I can't afford to do that with all the pickups, but the Lace Sensors intrigued me. They do indeed add to the sustain of my Strat, and I really like that sound. I went with the Gold, because it kept the overall balanced tone of the SSS Strat. They have good clarity - and did I mention the sustain

- and if I wanted it, I could get a reverse wound middle pickup to help with the hum that single coils can have. I didn't go that way, because I don't do studio work. I'm a hobbyist that occasionally gets to perform (most of my performances are either behind a drum kit, or with an acoustic-electric in my hands).
That's all I've got to add, other than to say thank you all for sharing such valuable information. I'll just sit back and continue reading now.:hmm:
