Request. This is your standard Rangemaster, but with a 5K trimmer instead of the 3K9 to help bias the transistor, and 6 switchable input caps to go from treble boost to more of a full range boost. It would be easy to add a 3PDT toggle to switch between a germanium or silicon transistor, but I would expect them to bias differently and so don’t know how good it will sound switching to silicon when the transistor is biasd for a germanium.
As always though, have a play with the circuit and see what you like, and remember if you want to use this daisy chained with negative ground effects, you could always use the Negative Voltage Converter.
