MXR Envelope Filter

[petemoore]

I dont' know what's up with trying to download from Tonepad...I can't even get their 'having problems downloading' page.
 I anyone could send a schematic my way of the MXR envelope filter...I could probably use it.
 I have Nurse Quacky 'on the payroll' and sh'e pretty neat...I would like to compare...and/or hear comments from those who have compared these two.
