Hello folks, just discovered I may have a nickel allergy and all the tuners on my guitars are Gotoh split shaft nickel. I really like split shaft tuners and do not want change to solid shaft. It does not look like the tuner buttons can be changed but thought maybe I just don't know how it is done? My other brilliant idea is to dip the tuner buttons clear plasti-dip which is the plastic coating used to make tool handles. Luckily I have stainless frets and have started experimenting with nickel free strings. Not sure the brief amount of time I spend touching tuner buttons is going to be an issue but it might be a good idea to eliminate as much nickel as possible. Thanks for any feedback, all the best.
