The hollow ball beater emulates the impact and sound of your palm on a cajon front plate and allows you to play bass drum patterns with your foot. It frees up both hands to play intricate snare rhythms or to add hand percussion. The Strap Drive Cajon Pedal is great for low volume applications where a drum kit is too loud. The Strap can fit any cajon depth from 10 1/4 to 13.5''. The new updated cable housing mount and cam arm angle allows for a smooth pedal stroke and prolongs the life of the cable.
