That looks like a neat PCB.
By the way - I built two of these last week for a friend. He wanted them built with internal presets, so that he could set them up as he liked, and get exactly the same result every time when he stood on the footswitch! I used BC109C transistors (I've recently found a big box of them dated 1977!), and they don't hiss at all.
