Thanks, Mike.  I'll double check them. 

I've got an extender coming tomorrow, so I'll be able to grab some measurements at that point, too.

Ok, editing this thing for updates.

I have signal!  But it's low except in the highest position.  And it seems to be correct in that position... wide open and distorted (the distortion actually sounds kind of nice!).

I have reflowed all input control solder joints, including those on the Grayhill board.  Any thoughts on what might cause this low output until I get to the last setting?

Check your gain switch resistor placement and soldering. At full gain you bypass those resistors. As you turn it down you start adding them from lowest value to highest value like a ladder.

Found it!  I had mixed up R3 and R10.  Changed those around and all is well.  Thanks, Mike!
