Vox / King Octavoice I. This device was designed to take an input signal (from a clarinet) and create sounds that are dropped down one or two octaves, making it sound like a bass or contrabass clarinet. There is another setting designed to make the clarinet sound like an oboe. But don't let the clarinet designation on this unit limit your thinking, this can be used with any input signal. The input is 1/8" and the output is 1/4" and there is a belt clip on the back of the unit.
