Clone of the Schumann Lion, but with a twist! Lion #29 is a normal production Lion, but #52 was a custom ordered model, which included a master volume control! The master volume increases the overall volume control of the overdrive and clean signals. We decided to build the circuit to include both versions, with a toggle switch that allows you to choose which version you want to fly with. #29? #52? Win, win!!
