"Collection only due to the value of the pedal"
As it no longer works as a pedal I think he means the value of the paperweight—which is probably about a tenner on a good day.
In recent JHS video, there was a blind shootout between Josh Scott's original Klon and a £23 mini Mosky clone. in the admitedly unscientific test, the cheapy was deemed the better sounding pedal. I have the mosky on my guitar board and it certainly sounds good enough to me.
