Hey yall, I have a Squire Tele that is modeled after the blacktop series (HH). I recently replaced the pickups with Seymour Duncans and they came with Chrome covers. I have them wired in correctly and they respond like they should to each position of the 3-way switch. However, there is a hum when the switch is in the neck and bridge position. If I touch the pickups while in the neck or bridge position the hum goes away and sounds really quiet. When the switch is in the middle the hum is also gone and I know this means that they are out of phase. But how do I get rid of that hum in the neck and bridge positions? Do I need to ground the Chrome covers? How would I do that? Just run a wire from the chrome pickup to the back of a pot and solder both ends? There is not a grounding tab on my chrome covers like I have read about on the web. Thank you for your time and response.
