My G6122T-59 VS Country Gentleman has Grover Imperial tuners with the butterbean buttons on it. I own three string winders – one for a drill and two manual – and none of them will fit onto these buttons. Winding the strings by finger is a pain. I've even took my guitar to a local guitar shop and none of their string winders will fit. Does anyone know of a string winder that will fit these buttons? I would prefer one that goes into a drill, but would settle for manual operated over doing it via finger.
