Mr. Muff is a German company offering stick and beater attachments designed to soften attack, limit dynamics, and achieve a round, puffy tone in seconds. The Muffstick drumstick attachment comes in two weights—Light and Heavy—and the Muffkopf bass drum beater cover is available in Standard and Deluxe sizes. We received both Muffkopfs and the Muffstick Heavy to review.
