Muff Booster test

The simple Muff Booster. This is a very simple circuit distorting project. Surely many people familiar with the legendary Electro Harminix from Big Muff guitar pedal. Many famous guitarists among almost as standard tools. this circuit, only a part of the original. One distortion segment. The electronic parts type of not sensitive, feel free to experiment with different types transistors and diodes, so a little bit different sound can be produced. The diodes and transistor should be placed in a socket to be easily and quickly replaced. We tried out the following components: 2N2222, 2N5088, 2N3904, 2N2222, BC108 transistors and…
