The RTOM Moongel muffle set has numerous advantages by its nature in the form and consistency. The self-adhesive surface allows the dampers in place to stay and not risk unnecessary sound changes as you play. Targeted disturbing overtones can be eliminated through the simple attachment to the drums or cymbals and be positioned differently when needed to create the right sound respectively. The muffles are washable, so they retain their adhesive consistency and remain usabl for a long time.
