I bought these pickups to replace the default ones in an Ibanez AF55 which sound extremely dull and have too much output. Now it's like a completely different guitar. They are very open and clear - they sound very similar to the single coils in my Telecaster.
I mostly play clean tones, or with a bit of hair, and I'm extremely happy with them. Keep in mind they are unpotted, so they are microphonic when you hit them with your guitar pick, for example. I haven't tried high-gain sounds with them, so I can't say how sensitive to feedback they are.
Their build quality is very high and installing them was easy.
If you're looking for some pickups for clean, jazz, tones, I strongly recommend them.
