Can anyone assist-Thank you

I think in Mark Hammer's site you will find a pack of Maestro schematics. The FZ-1B is inside of it.

Here's a .ZIP file containing the FZ-1 and FZ-1A schematics as well as the original manual:

Look down the page for "Maestro".

Oh, the FZ-1B!  Duh....

I think there were two versions of that one, based on a recent discussion on the "other" forum.  Here's a link to the later (version 2) schematic:

Search for "maefuzz.gif".  But note that there are errors in the "squelcher" section of that schematic, which was discussed in the above-mentioned thread.  Also, contrary to what the notes on that schematic suggest, the transistors are not germanium (IIRC, Dan N said the house numbers crossref to 2N3391A)... and it was not the fuzz used on "Satisfaction" (that was the FZ-1).  But it *does* have that gratey '60s-fuzz sound.  

Is there anything we might be able to help you with?
