You need a new and simple Distortion effect? Really Simple? Look at this 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…
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. BC547 transistors and used ECC82 or 12AU7, so the circuit operates at low voltage. Tube circuit provides classic, warm sine wave tremolo tones.
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:
New real tube distortion guitar effects. Mini tube amp, very full sound, beautiful tone. With 12AX7 tube distortion pedal made.
