So, I've taken my Bigsby B7 on and off of my LPC twice now. I can't seem to keep the G string from going out of tune. Actually, it goes out of tube without the Bigsby. The tuners are Schaller clones of the original Grover Rotomatic tuners. I don't recall ever having and issue with the stock tuners, but I know the German made Schaller's are some HQ tuners. I'm just sort of stumped on what's causing it.
