Just a quick hello, I'm glad I found this forum, what a great resource.  Right to it: I'm wondering about a BOM and some photos/comments about successful Dr. Quack builds.  I'm searching the forum and finding problems and answers, looking for a build with accompanying parts list.  Thanks in advance.

A big welcome to the forum.  If you're an intermediate or experienced stompbox builder the Dr. Quack is a nice auto wah.  For a nice simpler take on the Dr.Q the Nurse Quacky at home-wrecker.com is a great sounding filter.  Easier to build and use then the Dr. Quack although not by a lot.  I used yellow LED's instead of red ones and was able to use a TL072 or TL082 instead of the LM358.  I like the simplicity of the Nurse Quacky when recording.
