Mooer Envelope Analog Auto-Wah

The Mooer Envelope Analog Auto-Wah is a compact auto-wah designed for both guitar and bass. An auto-wah, sometimes called an envelope filter, opens and closes a filter automatically in response to how hard you play, producing the quacking, vowel-like sweep that players usually get by rocking a wah pedal by foot. With the Envelope, that sweep happens on its own, driven by your picking dynamics¹.

Mooer's Envelope sits in the same family as the brand's other filter-based designs, such as the Mooer Wahter, and it is aimed at players who want wah-style movement without working a treadle.

What it does

The pedal tracks your playing and sweeps a filter accordingly. Writing in a 2025 buying guide for gearnews.com, Julian Schmauch described the range of sounds it covers: "the Mooer Envelope packs plenty of character, from subtle quack to funky, vocal-like sweeps"¹. At the low end of its response that is a gentle quack behind your notes; pushed harder it produces the pronounced, vocal sweeps associated with funk and envelope-filter parts.

Because it responds to dynamics, picking strength and input level shape what you hear: play softer and the filter moves less, dig in and the sweep opens up. That makes it a pedal you play rather than set and forget.

Controls

The Envelope keeps its panel to four knobs, each aimed at a different part of the filter's behavior¹:

Together, Schmauch noted, these "allow you to fine-tune its dynamic response and sweep"¹. In practice, Sensitivity and Decay determine when the filter opens and how fast it closes, while Q and Tone shape the character of the sweep itself.

Price and availability

At the time of the August 2025 buying guide, the Envelope was selling for $58 in the United States, with UK and European prices of £52 and €59 respectively¹. That places it among the more affordable auto-wah options in Mooer's compact range.
