I shielded a Strat with copper tape, installed "noiseless" pickups, and I STILL get annoying single coil hum. The guitar buzzes pretty loudly until I turn to a position to where the noise goes away. I thought I did a pretty thorough job of applying copper tape but maybe I did something wrong? I will add the disclaimer that I notice this most when sitting next to my computer, so am I to deduce that even shielding won't stop single coil hum is all circumstances? I DON'T hear noise when playing this guitar in other environments but I tend to play next to the computer at home. Would one of those hum debugger devices solve this? They are a bit pricey but if it would work I'd give it a go. It's a little frustrating after going through the shielding process and not seeing good results. I want to shield a Tele also but won't if I can't expect it to make a significant difference.
