Re: wet Duncan 78 model
do you have any coil tape around? if so, just replace it. or at least pull that tape off to see if there's something else at play. or call Seymour Duncan, since 99.9% of the people here are just end users like you.
better yet, I'll do you one better. if you think you just can't live with it, send it on over here. I won't even charge you for taking it off your hands. there...problem solved. that's how I roll...always thinking of the other guy.
