Simple distortion effect with TL072

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

12AU7 Tube tremolo

This is a Hybrid tube tremolo circuit. It is interesting that a low frequency oscillator (LFO) in electron tube is not resolved, we do circuit transistor for low frequency.

Tube tremolo circuit
Tremolo schematic

BC547 transistors and used ECC82 or 12AU7, so the circuit operates at low voltage. Tube circuit provides classic, warm sine wave tremolo tones.

Tube overdrive effect

A lot of effects pedals has been prepared, including the famous Tube Screamer to mimic the old natural distortion of a tube amplifier. These pedals operate a semiconductor basis, more – less successfully mimic this sound. I did this and I use it with great joy:
