ZALMER TWIN, THE FIRST DOUBLE BASS DRUM PEDAL! Beaters may not be original. Will need one new spring. Very cool rare item! Feel free to offer suggestions to make Johnzdrumz better! Keep me in your favorite sellers. My inventory changes constantly, so if I dont have what your looking for, chances are I will soon! I play and share the same passion for bangin the bongos just like you! Thanks for checking out JOHNZDRUMS!!
