Analog envelope filter for electric bass

The MXR M82 Bass Envelope Filter is a classic auto-wah that brings any Bass sound to life. With its precisely adjustable analog circuitry, the Bass effect pedal delivers both classic funk sounds and experimental tones with synth character.

Precise setting for the envelope filter

The M82 Bass Envelope Filter's Sens knob adjusts how sensitively the circuit responds to attack, determining the basic response of the filter. The Q pot determines the bandwidth of frequencies swept simultaneously by the filter, while Decay adjusts the stop frequency. Separate Level controls also allow mixing of effect and dry signal in any ratio.
