For this design we decided to keep it loyal to the original Plexi by Wampler, we just added another bass boost option for the toggle, having the stock version, stock bass boost, and the third position with a 220n to give you a deeper boost on the bass frequencies.
Just wanted to mention, that the tone potentiometer is quiet powerful, so don’t get fooled by the fact that it’s just the three Knob version. This PCB it does not require many parts, what makes it either a quick and rewarding build or a nice entrance in the world of building DIY Stomp boxes.
One thing to keep in mind. J201 getting harder and harder to source. Use a trusted shop to get them. In all our projects we always give you the option to choose in between the standard transistor package or the SMD version, which we strongly recommend to go for, it has shown to be much reliable in terms of quality and availability. One final recommendation is to watch the size of the 470uf electrolytic capacitor when you’re sourcing the parts by yourself. They can be really tall what requires some creativity to make them fit in a small enclosure
