Problem with Mxr dynacomp and Mxr envelope filter.

[HitTive]

Hi, I made Mxr dynacomp from tonepad, When the pot sustain is max effect  making strange noises. When the pot sustain is 90% sound is good and effect work.

And second think:
I want to make envelope filter http://tonepad.com/getFile.asp?id=113 . I printed this: http://img859.imageshack.us/img859/9165/dpdtd.jpg . This is good wiring?
