Three function selectors vary the filter circuitry directly and offer a host of sound variations:- hot, funky sounds, biting heavy riffs and out-of-this-world Space effects. The Earth and Quake selectors can be used in combination to produce a total of 12 sound configurations. The Earth selector switches between three different frequency ranges and the Quake knob is responsible for the "Q-Factor" - altering the band width of the filter. The mini switch lets you change instantaneously between Modern and Classic modes, where "Classic" represents the familiar wah-wah effect while "Modern" supplies the opportunity to create new and subtle variations by mixing the effect signal with the original input. The mode is indicated by means of the LED. For the Modern mode a trimming potentiometer on the circuit board governs the mix between the original and effects signals.
