MXR Pedal FX Bass - Envelope Filter is a pedal that delivers classic envelope filter sounds, with fully analog circuitry for a rich, organic tone and separate DRY and FX level controls to preserve the bass.

Enjoy true bypass: connect a cable from your bass to the bass envelope filter's INPUT jack, then run another cable from the bass envelope filter's OUTPUT jack to your amplifier.

Start with all the controls at the 12 o'clock position, engage the effect by pressing the pedal, and turn the DRY knob to the right to increase the volume of the unaffected signal or to the left to decrease it.
