Description

Edit description

Introducing the MXR M82 Bass Envelope Filter, your secret weapon for achieving that classic funk-infused tone. This pedal is designed with the bassist in mind, providing envelope filter effects without compromising your low end. It's all about versatility with the M82, allowing you to blend the perfect ratio of direct and effected bass signal to achieve your desired envelope filter tones without losing definition.

Equipped with Decay, Q, and Sensitivity controls, the M82 offers a wide range of tones. The Decay control adjusts the length of the sweep effect, while the Q control affects the bandwidth of the filter, and the Sensitivity knob adapts the pedal's response to your attack and output level.

The M82 is built for resilience on the road and in the studio. It's housed in a rugged, lightweight aluminum chassis that can withstand the rigors of transport and stage use while taking up minimal space on your pedalboard. The pedal's power supply handles voltage mishaps and reverse polarity connections with ease, and true bypass switching ensures your tone remains intact when the pedal is disengaged.

Well-Built But Not for Everyone

The MXR M82 is widely regarded as one of the most established envelope filter pedals for bass, and it's clear that many players are highly satisfied with it. However, in my experience, it hasn't quite met my expectations.

To achieve a usable effect, I found myself needing to set nearly all the controls close to their maximum values. This felt somewhat restrictive, as it left very little room for subtle adjustments or tonal variation. Interestingly, I’ve had better results with the Carl Martin Ottawa, a pedal not specifically designed for bass, which responded more effectively in my setup.

Despite spending considerable time trying to optimize the settings, I was unable to resolve this issue. While I recognize that the M82 is a solid and well-respected pedal, it simply didn’t suit my needs.

Not Just For Bass!

I got this hoping to get more of a Claypool sound out of my bass-playing, but when I played my guitar through it I was pleasantly surprised. You can get a tone similar to some Frank Zappa stuff with this, and I often use it in conjunction with my Lo Fi pedal to get a squirting 8-bit sound that is really weird, which I love.
