Guillaume Fairfield is another one of the good guys who has been very helpful and open about his circuits during discussions on the forums. If you like the effects then consider supporting the builder and buying something from him in the future. If you want to try one before you buy then this may be a good starting point. This layout omits the mosfet used for polarity protection and just uses a Schottky diode instead.
Info from Guillaume about the original:
Have you ever sat in a barber’s chair wishing your tone was as slick as your freshly shaved upper lip? With the Barbershop Overdrive on your pedalboard, you could keep your moustache and sound good doing it.
The Barbershop is an original design, not a clone.
Raw, gritty, warm, smooth, open and transparent are all terms that have been used to describe this overdrive. It sounds great with any setup, but truly shines when used to dirty up a tube amp.
