Straight forward question. I have a feeling my E string roller moved from its position (I have it set a bit to the left side) more towards center last time I had a band practice. I can't fathom how that could happen since it has to roll. I did dig in quite a bit since it was a long time since we played. I'm not 100% sure that happened since I was messing with tuning day before and I could have accidentaly rolled it that time when I really really downtuned it. Anyways, I'll know for sure this Friday since we have a gig and see how it fares. Could it move from vibrations and/or hard playing? If so, I'll just get a bridge with fixed saddles. Anyone had this happen?
