    Hello, everybody.
    I´m creating an amplifier with mic amp specially for electric guitar.
    Now, i just wanna know what, can i use 2 mono amplifier circuits insted of mic preamp.
    What is the different between mic amp circuits and audio amplufier circuits.
    I´d already build an studio amp with TDA7297, so I wanna add micamp circuit to it.
    I´m trying another mono amp with TDA2030.
    I´ll join mic jack input to this mono amp and next step output to studio amp.
    What will different from an amp with micpreamp circuit?

    Mic amplifiers usually have a frequency response of 300hz to 4khz, and have a high input impeadance, as this is the normal range for speech, whereas an audio amp for guitar or music will have a wider range.

    The TDA2030 will not make a good mic amplifier if that's what you were thinking about. You need something intended for low level signals, perhaps NE5534.

    You need more components to use Mic amp circuit including 6 Volts of power and 2KΩ-6KΩ resistor (depending on the microphone in use)
