i wanna make a FM microphone for my guitar but the problem is that the electret mic itself output a lot of background noise even before amplifying its signal.
so obviously i need a preamp circuit but i don't need high gain or high volume. a low noise output with 1 volt peak to peak signal is ideal. but schematics i found online are relatively complicated and i don't know what they exactly do. so i would be greatful if anyone help with low noise preamp...
for the record this is fm transmitter circuit:
and microphone is just those ordinary mobile mics:
