Hi. I came across this guitar fuzz-distortion circuit. I am not sure how to start analyzing it. So far I have drawn the following four KVL loops:
Loop 1 (Green) = Vcc - Vce1 = R2*I2 - I3*R3
Loop 2 (Brown) = Vcc - Vbe = R1*I1 - R3*I3
Loop 2 (Pink) = Vcc - 2*Vbe = R1*I1 - R4*I4
Loop 3 (Blue) = Vcc - Vce2 = R1*I1
My unknowns are as follows:
Vce1, Vce2, I1, I2, I3, I4
Are there any other loops that I am missing? or what are two other equations I could use to set up a matrices? Also I really hate be a bother but could someone explain exactly how this circuit it working? I have been trying to get it but I do not understand, I really just want to figure out these kind of circuits are biased.
Best,
Ron
