The LP 1501 Cajon Pedal... 

Add a bass drum sound to you cajon with LP's 1501 Cajon Pedal! It's suitable for most  cajons in standard size, with a smooth and quiet cable system with adjustable spring tension.

Flexible positioning is possible with the cable being approx 90cm. Includes special mounting plate and patented beater which imitates the sound of a palm and thus delivers a warm and compact sound.

The wooden core of the beater provides a "natural feel" when against your cajon. Cajon not included with pedal.
