They came installed in a G&L ASAT Classic Tribute I just picked up. Mine has the open top covered neck pickup. I've had various Seymour Duncan and Dimarzios, Rio Grandes, Keystones, and Cavalier pickups in teles over the past 6 or so years, but these are my first set of Fralin. Out of all those pickups, I hear more "Vintage '50s tele" in them than any of the others. They say the neck is "stratty." I'd say it's strattier than a stock covered tele neck, but it's still not stratty to my ear. An 8k Cavalier Lioness I used to have sounded strattier (and a little better all around). The neck pickup is also a bit microphonic. I'm not blaming the pickup for that; these are supposed to be vintage sounding pickups, wound 5% hotter. Many vintage pickups are a little microphonic. The neck tone is fat, articulate and sweet. The bridge is bright and twangy but fat. Fairly hot. Very low noise for both. I think they're pretty good overall. But, had i spent $180 for them, I may be slightly disappointed. I liked the Rio Grandes a little better (same price), and the Cavaliers (Fat lion, Nashville, lioness) even moreso (for considerably less). These took a while to get sounding their best, between amp, pedals and guitar set up, but I am satisfied now. I plan on upgrading all the electronics and adding a 4 way switch. Will update this post. I'm gonna try to deal with the neck pickup microphonics with wax and surgical tubing.
