Hey guys, I installed the new pickups I received for Christmas and they sound great but I notice a humming or buzzing noise when the guitar is plugged into an amp. I'm not sure if this helps but when my hands touch the knobs and switch the buzz almost disappears and when my fingers touch the bridge the buzz increases a bit. Lastly when I touch the bridge pickup the buzz almost doubles in volume. Probably some grounding issue I'm sure but I like to ask for advice on these things as it's the first pickups I've ever installed. Thanks for the help.
