the first mute of it’s kind, a hybrid between traditional mute making and modern 3D printing techniques. merf has created the best mute you don’t own yet.

pairing our flexible top from the gumby and a traditionally spun metal bottom made by a master metal spinner (not flexible, duh) allows for the adjustability of our fully flexible gumby mute while creating the tonal colors and response of a traditional metal mute.

available in 5 (soon to be 6) materials: aluminum, brass, copper, bronze - x, and bronze - y.

all metal gumby mutes are shipped with both an acrylic and brass screw
