Quality Microphone, Guitar Preamplifier Circuits

There are preamp circuits that will be especially useful for musicians and guitarists, and there are quality tried and printed circuits. A very high quality design preamp circuit has stereo two-channel audio input/output and microphone input, as well as equalizer and volume control sections. Controlled by tl071 and tl072 opamps, the supply voltage of the circuit is provided by a 9 volt 300ma transformer.

Normally, many opamps work with a symmetrical supply, in this application, a symmetrical voltage is obtained from a single output transformer, so you should use the supply circuit in the file or you can make a standard symmetrical supply circuit.

Guitar preamp circuit 3 band equalizer distillation effect

Circuit tl074 and jrc4558 opamps based on the 3-band equalizer volume control, distillation effects section and selector switches are found. 2×9 volts ac 300ma transformer recommended for operating voltage 2×12 volt dc symmetrical power supplysformer in this application were obtained from a single so file must use the power supply circuit or do you do a standard symmetrical supply circuit.
