From the post
A few people have requested a vero of the Mastotron, so here it is. If you want to make it verbatim then you would put a 100 ohm resistor in series with the input wire before the pot, and a 100 ohm resistor in series with the 9V supply wire, but I personally wouldn't bother with either. So enjoy your Woolly Mastotron!
