Don't rush by the MXR M82 just because there's fatter, funkier envelopes out there. I'm pretty pleased with it for its versatility within my non-funk format.
The Dry knob enables you to push the fundamental tone out to the front and make the effect fairly subtle, something most envelope filters aren't known for. I like to set the Dry knob to about 2 o'clock and the Effect to 9 o'clock with Sensitivity at around noon using a Fender Am Dlx in active mode. I can play what sounds like an uneffected tone, then step up the attack to pull in a nice quack for emphasis: lay down a uneffected root, then hit the octave hard (QUACK!), throw in fifth and seventh sixteenths (quack! quack!), go back to uneffected root, etc., etc.,
You can, of course, go full-on 70s synth-y with the thing if you want to. But that's not a particularly useful effect in my band's format, but I find I'm using this pedal more than I thought I would because I can dial the funky cheese way back.
