What does the MXR M82 Bass Envelope Filter do?

This pedal creates classic auto-wah and funky filter effects specifically voiced for bass guitar. It reacts to your playing dynamics, opening and closing the filter based on how hard you pluck the strings. This allows you to achieve expressive, percussive, and vocal-like tones, adding a unique flavor to your basslines.

How do the Decay and Sensitivity controls work on the M82?

The Sensitivity knob adjusts how the filter reacts to your playing dynamics, letting you dial in the perfect response for your bass and playing style. The Decay control sets how quickly the filter closes after it's triggered, allowing for short, punchy effects or longer, sweeping sounds. Together, they shape the character of your envelope filter.

Can I adjust the Q (resonance) on the M82 Bass Envelope Filter?

Yes, the MXR M82 features an adjustable Q control. This allows you to fine-tune the resonance of the filter, from a subtle sweep to a more pronounced, vocal-like "wah" sound. Experimenting with the Q setting lets you sculpt the intensity and character of the filter effect to perfectly suit your musical needs.

How is the MXR M82 Bass Envelope Filter powered?

The M82 Bass Envelope Filter is designed with robust power supply circuitry that can handle over-voltage and polarity issues. It typically operates with a standard 9V DC power supply (sold separately).

Is the MXR M82 Bass Envelope Filter true bypass?

Yes, the MXR M82 Bass Envelope Filter features true hardwire bypass switching. This means that when the pedal is disengaged, your bass signal passes directly through without any coloration or signal degradation. This ensures your tone remains pure and unaffected when the filter effect isn't active.
