Mine is awaiting some parts, but in the meantime I wish to thank you, Johnny, for keeping it (Rev B) simple in terms of parts. I think there is a total of two resistors in the whole shebang whose values are not multiples of ten, and precious few caps altogether. I think if I was wiring this up on perf, I would try to include some kind of jangle-box option, but a I'm not, I won't--unless you have a suggestion as to how this may be easily done without carving up your nice board.
