I was rooting through a box of basement junk and pulled out a roller nut I never installed and don’t remember buying. It has a pair of tiny ball bearings caged on each side of each string slot. I’d like to hear from anyone who’s used one of these. Any future trem use I plan to do would be in the retro Bigsby wiggle spectrum, not the harmonics pulled five steps up followed by string flap dive bombs. So I may not need what it offers. Also, I don’t have a fresh set of the .011-.049 strings I use to check if those will even slip through the (tight-looking) string slots. Anyone ever used .011s with one of these? Did the roller nut impart any feel or tone difference you could detect?
