I just put one in a strat- 1 bucker 80's style. Ash body with maple neck and vintage trem. Sounds killer without being too hot or to underwound. Very well eq'd with a good balance across all tonal points.
Highly recommended unless you want dead accurate type unpotted PAF tones
Plenty of people rave about them... they seem like an excellent value if you're looking for a PAF-style pup.
I mentioned them to a friend who was looking to upgrade... he just said: "I don't like DiMarzio"... I thought that was rather close minded... DiMarzio was a pioneer in the pup replacement biz.
They do sound nice I'll say. It took me a little while to get used to them. Especially when switching guitars mid show. The tone is sweet. It takes a bit more push on the amp or pedal gain to distort than hotter pups though.
I put them in an Epi LP. Definite upgrade from what I had. Do I like them better than the Gibby classic '57's......not a chance.
