Advantage neto it allows you to do double pedal things while hitting your hi-hats in the close position, bali it drops your hats close allowing you to play double peds with uhhmmm well your hats closed, hahaha umikot lang. pero aun hope u get the idea.
disadvantage: cguro ung pag "drop" ng clutch, kakamayin mo un eh or siguro pwede mo paluin ng stick, parang nakakailang diba?
