I did not have the original board size and had to determine it by comparing it to the battery dimensions.
The board size may not match the original size, but I think it is a good approximation.
YAFF indeed. But those side mounted foot operated knobs are interesting. Not for a FF - I still don't know what the point of the fuzz knob is, and the level should be set-and-forget. But interesting for other applications, like the old MXR rubber knob boots. Not that I know from such things, but I imagine a perfectly suited knob can easily be 3D-printed. I wonder how well the pots would hold up.
