Our Answer:

Hi Sven, it sounds like you have a wiring problem. Most likely, you have the “hot” and “ground” wires backwards. Triple-check your 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.
