Sweeper

The Sweeper delivers envelope-controlled filter effects for bass guitar. The filter responds to playing dynamics, sweeping through frequencies as you dig in, creating classic funk bass tones.

Two knobs: Sense adjusts trigger sensitivity, and Q controls filter resonance. The envelope follower tracks your playing dynamics, creating wah-like sweeps that respond to attack strength.

Auto-filters became essential for funk bass, creating that quacking, synth-like tone without requiring a foot pedal. The Sweeper brings that effect to bass in Mooer's affordable micro format.

True bypass switching. For bassists wanting envelope filter effects without manual wah operation.
