I'm not nearly as pleasant as JB, but here goes anyway ... the tuners on the AS range are Grover Rotomatics and are available in a silver or gold finish. Essentially, most tuners will fit any guitar but the screw holes used for the Grovers will be in a different spot from the Gotoh's which are on some Avalon Gold's (and some do use Grovers). Grover tuners are easy to identify as they have an embossed 'Grover' on the casing.
