I would advise you to avoid this one, spend a bit more and get a quality humbucker.
I bought this for my project guitar just to see what a 25e humbucker is. Well, you get what you pay for.
The package contains the humbucker, a plastic mount, two screws and springs. No wiring diagram included. Properly packaged in bubble wrap. A plastic sheet on top of the humbuckers as a cover.
The humbucker has three wires: white, blue and bare. The quality of these wires is pretty horrendous. You can literally pull them apart with your fingers. The white and red wires are both just 4 strains of thin wire enclosed in a standard plastic tube. You can see that the build quality is cheap and soldering these was a pain.
I decided to desolder this as I don't really want this on my guitar next to the beautiful Seymour Duncan SSL-1's I bought earlier.
I would advise you to spend a bit more and get a proper humbucker. You'll be glad you did.
