I’m willing to make this circuit to plug the guitar to mic in port on my notebook. Since the signal im getting wiring the guitar directly is too low.
My notebook does not have line in port. only mic in (a combo trrs heaphone jack). I have to crank up both guitar pots and the mic port volume to maximum to get some signal.
I would like to know if are necessary any changes to the circuit to match voltage and impedance of mic port, to make it safe for mic in, like changing R1 and R2 resistors to 1MOhm. I dont want to damage the built in electronics.

Thanks
Celso
