Damn, this thing sounds incredible.  With the Strat plugged directly into it, it blows away my Ultra Fuzz.  I bought an OC140 from Small Bear (along w/some other stuff) and it worked great.  I breadboarded it, set the trim pots close to spec, plugged everything in and it just worked!  I'm playing it thru my Randall Plexi module with the bridge and middle pickups and it sounds ridiculously huge!  I love the touch sensitivity and volume cleanup too!  Dig those soupy-thick velcro-fuzz tones.

I'm a little worried about temperature variablility with the germanium transistor tho.  Have you guys had much heat-related problems with these?  What types of things can happen when they get to hot or too cold?

  I had a GE in a Green Ringer that was oscillating...the transistor became a 'heat theremin'...I could vary pitch by touching or gripping it.
  Yes.
  the bias arrangement can drift. I had a TB brought in from cold...it went Gachk/Blatt, that's it, one or more of the transistors cutoff the signal completely. FF's that act funny after playing them for a time...or depending on moon cycle or weather reports?
  There's a reverse diode trick for temperature stability, uses a Ge diode reverse biased across the transistors internal B/E junction diode..seems to work pretty well.
Convention creates following, following creates convention.

Since this one does not have a tone control, can a LPF or the stupid simple tone control work ok with this one?
(a LPF tone control works pretty good with my May Queen)

HEHEHEHE! YES!!!!! I need to build another one!

It's possible this will work.
