Bought these to replace pickups in an Orville LP Standard, and I have to say that I am very happy with the choice. I first had experience with these from an Epiphone Slash model and was very impressed. When I looked into replacing the stock Orville pickups, these were the obvious choice for me.
There is a Guitar World review of the Slash Epi with Paul, and I think this review will give you an accurate representation of the tones from the pickups. While most of you may be looking at these for that Slash sound, they are quite versitile. My luthier absolutely hates Slash as a guitarist (no offence, personal opinion) but absolutely loves these pickups and has stated they are one of his favorite SD sets.
I'm more a Van Halen than GNR fan, and I can get some great early VH tones from the bridge, and of course that classic Sweet Child / Slash solo tone from the neck.
Just buy them!
