The MXR M82 Bass Envelope Filter pedal provides classic all-analog filter-modulated tones to mix in with your signal while still maintaining the integrity of your bass's earth-shaking low end. The M82 features dry, FX, decay, Q, and sensitivity controls to shape your enveloping characteristics, all analogue circuitry, true bypass configuration, and is housed in a rugged and lightweight aluminum chassis that won't eat up too much space on your pedalboard. Give your signal the love it deserves with this award-winning envelope filter pedal!

True-Bypass All-Analog Circuitry

Your M82 features true-bypass all-analog circuitry, so you can be sure your bass signal is getting the best treatment possible before hitting your amplifier. True-bypass circuitry assures you that your tone doesn't lose any integrity or sonic characteristics while leaving your envelope filter pedal when it is disengaged. This baby's power-protected circuit ensures protection against over voltages and any polarity issues, and low power consumption gives your battery greater longevity.

Versatile Filter Sounds From Funk to Electronica

Your dry, FX, decay, Q, and sensitivity controls give you a lot of room to play around and dial in the exact dimensions of envelope effects you're looking for. The dry control sets your direct signal output level, and your FX control determines the output level of your filter. Move your decay control to set the decay stop frequency, and roll your Q control knob to adjust read more the intensity of the filter. Finally, your sensitivity dial adjusts the reaction to your input signal.

Tough Phase 90-sized Aluminum Chassis

The MXR M82 Bass Envelope Filter pedal will keep your signal going strong with its resilient yet lightweight aluminum outer chassis. Whether you spend most of your time in the studio or on the road, this baddie will be at your side with every stomp, making it a dependable companion for the gigging musician. Like the Phase 90, this pedal won't eat up much room on your pedalboard.

Wow this is a great envelope filter! I received it and can’t stop exploring. It’s pretty simple to dial in on the sound you desire the dry knob I keep it turned at like 9 o clock all the other controls at 3 o clock and I get a phenomenal sound. It sounds just as good as some of the more expensive ones. I purchased on the payment plan with zZounds and I’m very happy with this pedal. I did not have to use manufacturer support.
