Looking in this document:
http://www.geofex.com/Article_Folders/trem_face/tremface.htm
I was hoping someone could confirm the resistor values for r12 and r15.  Sometimes it's 2.2K, others it's 22K (parts list/millenium bypass schem/corrected schem).  I'm not sure if they're supposed to be the same or different.

I'm pretty sure the above schematic is based off the info at the bottom of this page:
http://www.foxroxelectronics.com/scrap.htm
and looking at the pictures provided it appears that there is a red/red/yellow resistor connected to the emitter of the bc184c
(ECB).  According to my calculations red/red/yellow is 220K, and that value didn't make it into the schematic.

Is there a definitive parts list?

What values have been used successfully?

That was a long time ago. I had to dig out my notes.

The values on the parts list work fine. R12 and R15 are 2.2k. I mistyped the value in the schematic.

The 220K is R7. It was 330K in the units I examined. The real value of that resistor is "big compared to 10k".  I put in 2M in one of my corrected versions.

The values used in the parts list have been used successfully, according to my build and to email I've received.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.
