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.
