So I fitted these on an old Fenix LP clone I was giving a make over... Here's what I found:
The pickups were easy enough to install, save for the thickness of the wire shielding. It required a little ingenuity to pull them through the routing - they were too thick to simply push through. But we got there in the end, and this is only a one time issue - once it's done, it's done.
Obviously, this is the main one. We went from a generic humbucker sound, to a massive and rich sound, with real character. When playing through a medium/high gain, it just sounded great.
The bridge (JB) has a lot of bite, but dialling back the volume gives a crunch that doesn't hide the fact there is a lot in reserve.
The neck (jazz) was rich, warm, round - a perfect lead sound. Rolling back the volume and it started sounding deliciously bluesy.
These pickups have given an old guitar a whole new lease of life. If you want a sound that can go from rock to metal with a twist of the volume control, then you could do a lot worse than this set.
