Alright I was scanning a yard sale a few days ago, and I found this really cheap Fender Telecaster imitation by Yamaha. Now this guitar has the greatest action I've ever had the opportunity to play. So naturally I bought it, brought it home only to be dissapointed by a hum that only comes through on the lead channel (which is necessary for metal!). So I need some help on what could be causing the issue! I've posted some pics below for your convenience in diagnosing the dilemma.
I DON'T KNOW WHAT THIS IS BUT IT'S LOOSE!
