Simple distortion effect with TL072

| 0 comments

You need a new and simple Distortion effect? Really Simple? Look at this circuit:

Simple distortion effect circuit, few parts, real guitar distortion sound.

The simple distortion efect circuit.

Not too demanding parts. But the voice .. hmm. Indeed, only a few spare parts required. The circuit is the “soul” of the tl072 chip. It is built around the circuit. And, of course, add garnish. Well, actually distort the character of the D1 – D4 diodes is given. In this case, two 1N4148 and two 1n914 diode. cut the signal. This results in a symmetrical but powerful cut. or maybe the solution according to their own ideas, but you can choose a sound character. even the parts is not too critical. I recommend them to feel free to experiment. Perhaps trying a different opamp is that it leads to what sound will surely hear some variation. the completed circuit can also change your tone of options. Examples: tone controls

Distortion effect test




In this circuit, as shown in the drawing, two 1N914 and two 1N4148 diode cut the signal. They can feel free to vary. For example, germanium diodes will result in the rough, loud sound. Red LED to a softer tone. If the circuit is to be a pre-amplifier, the sound is stronger and develop little rougher (“boost”).

We made a test video that is pretty much what’s voice:
