The “fo-SHO” is a very popular and simple booster. This layout is pretty sweet as it mounts right off the back of a standard 16mm pot, making it easy to add a booster to multi-pedal projects. Self contained! The “fo-SHO” works superb for pushing the front end of a tube amp or even boosting before an overdrive/distortion for more gain. Inspired by the Super Hard On, this simple circuit really boooooooooosts great.
You can etch your own single sided layout in your home lab of doom from the Build Doc or if you are lazy (like me) just mosey over to OSH Park and get 3 boards for about $3 shipped to your door. Enjoy!
