The control consists of four potentiometers, one each for frequency, duration, tempo, and volume. The first three are simple 100K linear pots wired as voltage dividers. The fourth is a 100k audio taper wired in the traditional volume circuit. The switches for each of the slots are simple momentary SPST devices and another is added for the start stop function. A central red LED is wired in as a tempo indicator.
