I came across this while browsing one of the usual forums recently and thought it looked like an interesting Rangemaster variant.   Silicon or germanium transistor, variable boost, quiet, standard power supply…  seems to have a lot going for it as far as treble boosters go.   

Here’s the thread on DIY Stompboxes (Peter is FSFX) and there’s this documentation detailing the noise reduction.

Naturally the input caps can be tuned to taste, and the range pot can be completely removed or replaced by a switch if that’s your preference.
