I have an old worn black metal pickupring I want to put on my batwingStandard, after Cerebral Gasket revealed this little cool trick in another thread. http://www.everythingsg.com/threads/gibson-sg-classic-2007-vs-2016.35266/#post-515332 I think my metal pickup ring is from the late seventies or so. But I have some questions: 1. Will a metal pick up ring produce any kind of interference/statics/noise or have any effect on the magnets in the pu? 2. Did Gibson use metalrings consequently on some models, some years? 3. Does Gibson still use them on Historic/RI guitars?
