I bought this set for my Squier CV 50's Strat in order to get closer to the Frusciante sound like many fans do. Let me talk about the pros first, the pickups are definitely high quality and they will give you a clean, vintage Strat sound which is ideal for classic rock and blues. The neck pickup can get you close to the clean Gilmour and Knopfler tones easily, while the bridge pickup is very Hendrix-ish.
However, it sounds a bit darker than I expected with the crunchy tones. If you read that Frusciante used these pickups in his favorite guitars and decided to buy this set, don't. Frusciante got confused about which pickups he used, he actually has Fender stock pickups in his main guitars, confirmed by his guitar tech. His clean sound is not that clean, it is crunchy, thick and warm at the same time, and these pickups are just not the ideal fit for that.
That said, I'm definitely intending to keep these pickups for the pros I mentioned.
