The Steiner Crumar EVI is a black electronic valve instrument from the renowned brand Steiner. This innovative device allows users to create unique and expressive sounds by manipulating electronic signals through a valve system. Perfect for musicians looking to explore new sonic possibilities and add a modern twist to their performances. The Crumar version is exceptionally scarce, with only about 500 units ever produced. Early hand-built units made directly by Nyle Steiner himself (EVI-II) are even rarer, with only around 200 units in existence. Because of their age and the delicacy of 1970s analog electronics, finding a fully functioning model is highly unusual.
