Simple Overdrive Effect Pedal

This is a very simple overdrive effect. There are a lot of same kind of effects on the net, but I decided to design something simple. It's a great beginner project.

This is me playing with it:

First I play clean, the switch on the effect.

Overdrive or distortion occurs, when signal is amplified too much. Amps have an upper limit of volume. If a sound signal is louder than then it's peaks are simply chopped off. That is called clipping (distortion).

We can simulate clipping, by placing diodes between the signal and ground.

Now it's time to build one for yourself too!

This is what you need:

6.3mm stereo female jack
6.3mm mono female jack
DPDT switch
0.1uF capacitor
LM386 op-amp
220uF electrolytic capacitor
47k resistor
100k resistor
red LED
two 1N4148 diodes

Incase you don't know, how to read schematics, there are a plenty of tutorials available. Just Google
