I play a Weber Fern and love the sound, playability.... but am totally disappointed in the Grover Tuners that it came with. These are rickety and feel cheap. Not at all what one would expect from an instrument retailing at over $6k. On my guitars, there are many options for smooth, accurate tuners (Gotohs, Waverlys, etc), but for Mando is the only choice to spend another $500 for Waverly tuners? And with that, do they feel better than the stock ones? Is there an alternative? I've read that Gotohs are good for guitar, but not great for Mando. What options are there for a smooth, accurate tuner for an F Mando please?
