Haven't been on here in a loooong time ... but glad folks are still digging my envelope filter. This is a clip of the current iteration from an outdoor gig last summer -- that's a lefty Matt Moriarty Wolf guitar straight into the AX8 and straight out to the board. I use an Atomic CLR Neo onstage.
This was one of the last shows we played before the lockdown happened ... if you go to about 1 hour 16 minutes in you can hear the filter with the parameters reversed (this would be like changing the drive button on a real Mutron from up to down). Requires some tweaking of the slope to make it work but the harder you pick the more it goes "thunk" (closes instead of opens). That's a version of the 76-81 take on Dancin' in the Streets the Dead used to do, including the cool diminished chord jam toward the end. The whole show was also a lefty Tiger guitar into the AX8 direct to the board, no other pedals, etc.
I have found that the AX8 is highly sensitive to the guitar you are using, but the basics for what I do to get the Garcia tone happening are simple ... Twin (Double Reverb) block, Plus Distortion block, the wah block to do the envelope filter as detailed earlier, pitch block to octave double, phaser, delay. Using the guitar's onboard effects loop helps tremendously, as it does with the real analog gear. Cabinet block is the old JBL E-120 IR that Jay helped me make back in 2010 or so off my real Hard Truckers 2X12 with JBL E-120s. That's floating around everywhere. Reverb is the vintage spring adjusted to taste. Middle pickup single coil 95 percent of the time, occasional bridge as a humbucker.
One really important thing about the envelope filter that I probably mentioned earlier ... your touch on the guitar has a tremendous amount to do with setting it so it will open easily all over the fretboard. Set it so it opens easily way up high on the fretboard (that is generally where it's hardest to open it), then lighten your picking touch to make it open/close correctly down on the low notes. This is where the onboard effects loop on the guitar really shines, as the envelope is seeing constant signal level from the pickups regardless of where the guitar volume is.
Have fun!
