Replaced the original Tuners on my DBZ Cavallo with these, and gotta say - I'd never go without locking tuners ever again changing strings and tuning is a breeze, simple as it gets, and tuning stability is as good as it gets. Even in my "climate challenged" house, i rarley have to really re-tune that much. The Hipshot tuners look awesome with the open design, and functionality couldn't be better. Will successively replace all tuners in all my guitars wi locking tuners, I don't see the point if non-locking tuners anymore ;-)
