Precision pickups and when I touch the pole pieces on the pup that is closest to the neck I get a nasty humming noise. I never noticed this problem before I installed copper tape wound strings. I heard that these strings can cause noise because they are not coated and prevent grounding from touching but how does that relate to the problem I have? Even if I don't touch the strings if I touch the pole pieces on the front pup I get the noise? I am guessing this is a grounding issue that can be fixed and the copper tape wound strings are not the cause? Just my luck this happens to me after a long long tone search with various strings and these copper tape wounds I finally feel I found the perfect string and then this dang problem surfaces. I appreciate any help at all. Thanks.
