Hi you all trying to build up my first pedal, a muff fuzz replica actually, following up the schematic you'll find in the attachements. Problem is...it doesn't really work at all. I arranged the circuit on a breadboard but all i can hear from it is a tremendous issing. I noticed that after the C3 capacitor (100nF) that feeds the volume pot the signal gets completely shut off. Tried also to increase R5 (10Kohm to 68Kohm) thinking it might wouldn't feed the transistor properly. Does anybody have some advice?Thanks in advance
