Based on the original Stage 3 Booster Circuit but does a whole lot more. You can use it just like the original Stage 3 but when you stomp on the 357 Mod switch you now have a Dual Stage 3 utilizing both the original FET design in tandem with the kick of a 2N5457 FET behind it for some extra bite and growl.
The dimensions of the pcb are 38x34mm.
