Reader Question: Why is My Classic 57 Humbucker Thin and Humming?

Gibson Classic 57 humbuckerMost likely, you have the “hot” and “ground” wires backwards.

Sven Writes:

I have a Gibson 57 Classic Humbucker, which has a really high output of 9K!! and it’s NOT an classic+, which I know. I installed it by itself in the bridge position, with the selector on treble, and it sounds thin, very quiet, and is humming slightly. What could be wrong?

Our Answer:

Hi Sven. It sounds as though you have a wiring problem. Most likely, you have the “hot” and “ground” wires backwards. Triple-check the wiring diagram that came with the pickup. If you can confirm 100% that the pickup is wired correctly, then try touching the hot / ground wires directly to a guitar jack, and tap the pickup. There should be a loud and healthy “thud” that comes out of the amp when you do this. If not, then the pickup is damaged.
