noob question.

Recommended Posts

hi, i have been reading a lot of articles on the web about preamps. consider the schematic on this page: http://www.till.com/articles/GuitarPreamp/
wouldnt that just give a fluctuating DC output(like wave2.bmp), instead of AC(like wave1.bmp)?

please help, i dont get this.

The output is supposed to be an AC signal with an average DC voltage of 0V.
The article says, "C1 is a coupling capacitor to remove DC from the output." So if your circuit has DC on the output then C1 is shorted or connected backwards, or the load has DC on it.
