From the post
Happy #fuzzfriday, everybody. The Mastotron is a heavy silicon fuzz and a variation of the Wooly Mammoth. It can produce a wide sonic range from 8-bit sounds to complete wall-of-fuzz tones. I've drawn this up to fit in a 1590B more conventionally than the Zvex way. You can use PCB-mount right angle pots, mounted from the solder-side of the board.
I'm going to try and start including drilling templates with layouts that have board mounted pots (or at least the right angle kind). As I have time, I'll be going back to previous layouts with board mounted pots and creating templates for them as well. You can find them in the new Drilling Templates tab at the top of the page. You can find a 1590B drilling template for this effect here.
