M-120 Envelope Filter

The MXR M-120 Envelope Filter is a captivating sonic chameleon that can transform your guitar's voice into a whole new realm of expressive, shape-shifting tones. This voltage-controlled low-pass filter allows the amplitude of your playing to dynamically control the "brightness" of the sound, creating the iconic "wah-wah" effect that has graced countless classic recordings. At the heart of the Envelope Filter's magic are two intuitive controls: Threshold and Attack. The Threshold knob adjusts the sensitivity of the filtering, while the Attack control determines how quickly the filter responds to the dynamics of your playing. Crank the Attack all the way up, and the filter will snap into action with lightning speed, delivering a sharp, percussive "wah" at the start of each note. Dial it back for a more gradual, vowel-like sweep that ebbs and flows with the natural articulation of your performance. This versatile pedal has been a secret weapon in the arsenals of genre-spanning artists, from funk maestros to psychedelic explorers. Jimi Hendrix famously used an Envelope Filter to conjure his otherworldly guitar tones, while modern players continue to harness its expressive potential to add new dimensions of texture and emotion to their sound. Whether you're laying down funky rhythms or embarking on a mind-bending solo odyssey, the MXR M-120 Envelope Filter is a must-have tool for any guitarist seeking to unlock a universe of dynamic, shape-shifting tones.
