90pF/mt is still not that low C. Of course, you didn't specify how long the cable is, so the C/mt value is irrelevant by itself. Personally, I'd only use ~5' of that cable. Anyway, just turn off the noise gate for now. You have noiseless pickups anyway. Try plugging straight into the amp first. Nothing more I can add here. Good luck.
