Jen Harmon Booster
Not sure what to call this. It has "Booster" written on the original unit, but still i think it's rather closer to an overdrive than a booster. It's definitely not a fuzz. Either way, it does sound pretty nice in the demos. There are other layouts for this circuit around the internets, but i thought i'd be cool to have one that's 1590B friendly. As usual, i've added polarity protection and a filter cap (220µ), to make yours per original, just omit those accordingly. Transistors were BC318C in the original, but i think our closest modern day analogy would be BC549C. Before anyone asks, Input goes to Gain pot's lug number 3.
