Distortion Pedal Circuit for Guitar Effects

Here is a distortion pedal, with noise-gate integrated setting and bass / medium / treble, operating on the sector. Personally I added a switch stop walking on food, a door fuse (fuse 500mA under glass) and led (220v) It is a fitting analog multiplexer controlled by two signals. One comes from the push through a memory removing rebounds parasite of the switch, the other from the floor noise-gate which compares the output level to a level
