Yes, the buzzing goes away if I tough the bridge or tuners. So, basically, nothing to be done other than remove them?![]()
I've not dealt with this issue drectly before so i'm not sure of this but you could try and remove a small amount of the coating where the string contacts the bridge. Though i'm not very confident this will work.
Do you get any of the same buzz with normal strings like say when you're not touching the strings with volume up. This could indicate some other ground issue.
