I've been using this pickup, which isn't expensive for a humbucker, for 6 months. I installed it on a home-made electric guitar, so it's hard to make any comparisons with commercial models.
That said, I installed it on the bridge and I'm very pleased.
- It comes with a short but adequate manual.
- You can use it as a single-coil or humbucker. The difference between both sounds isn't that big but as single-coil it is cleaner and less distorted, while still having enough output power.
- I had no issues adjusting the height of the pickup.
- It produces almost no noise.

Bottom line, it's a very good pickup, very versatile and not expensive, without being top-level.
