The Analog Kick Drum MKII is the same basic concept as MKI, in that you press the momentary footswitch to generate a kick drum sound, but the entire kick drum circuit has been redesigned for a fatter, broader, and more interesting sound palette. MKII also has trigger input that can be used to trigger the kick drum, like CV gate for example (0-5V). Controls for pitch, decay, distortion, and volume.
