Introducing our mountable MorF-16!!! This version of the Morf is made from 16 guage steel, giving it a higher pitch than the MorF-18 (other than that both models are exactly the same). The MorF-16 is an open ended bell and is equipped with 2 adjustable springs allowing for many different sonic possibilities. Rotate the spring in the mouth or adjust the spring on top to control different muting and buzzing sounds this awesome instrument has to offer (see demo video). The idea is to "MORF" the bell into whatever sound pleases your ear. The MorF-16 is roughly 11" x 6.5" and weighs about 3 lbs, making it easy to travel with.
