MOOER Sweeper Bass Dynamic Envelope Filter

The MOOER Sweeper Bass Dynamic Envelope Filter is a compact bass effects pedal designed to deliver expressive auto-wah, funky filter sweeps, and dynamic envelope-controlled tone shaping specifically tailored for bass guitar. Built as part of MOOER’s acclaimed Micro Series, the Sweeper provides responsive filter effects that react directly to playing dynamics, making it ideal for funk, fusion, slap bass, groove-based music, experimental bass tones, and modern performance setups.

Powered by an intelligent dynamic envelope filter circuit, the Sweeper automatically adjusts the filter sweep based on the strength and attack of the player's performance. Softer playing produces subtle tonal movement, while harder picking and aggressive slap techniques generate dramatic vocal-like filter sweeps and energetic wah-style effects.

The pedal features dedicated controls for Sensitivity, Resonance, and Decay, allowing bassists to precisely shape the response and character of the filter effect. The Sensitivity control determines how strongly the filter reacts to playing dynamics, Resonance adjusts the intensity and vocal quality of the filter peak, and Decay controls the speed of the filter sweep for everything from fast funk responses to smooth evolving textures.

Unlike many guitar-focused envelope filters, the Sweeper is specifically voiced to preserve low-end frequencies and maintain bass presence, ensuring that groove, punch, and clarity remain intact even during aggressive filter modulation. This makes it especially suitable for slap bass, fingerstyle funk playing, synth-inspired bass tones, and rhythmic performance styles.

Built with MOOER’s durable full-metal Micro Series chassis, the Sweeper offers professional reliability while occupying minimal pedalboard space. Its compact design makes it easy to integrate into both small and large bass pedalboard setups.
