The Electro-Harmonix Enigma Bass Envelope Filter Pedal is a bass pedal with controlled filters which are a unique type of sound modifier where the intensity of the effect is controlled by the user's playing dynamics. The volume and dynamic of the incoming audio signal is used to control a swept filter. As the volume increases or decreases so does the frequency of the filter. With three filter modes, along with some other controls, all of the classic Q sounds are available to the user. An analogue distortion circuit was created specifically for the Enigma, and adds a dynamic edge to the filters sound.
