Hello everyone,

My final project preparatory class study is the saturation of a guitar signal and more precisely the distortion from the MXR Distortion +.

In my study, I have already begun to reproduce this wiring diagram on LTSpice software to simulate the circuit and have references measures.

Also, I bought all the necessary electronic components and started reproducing the circuit.

The schematic is the following :

What I would like to do, is separating the circuit into parts and calculate the transfer function of each part to finally get a global transfer function of le circuit.

I think that I could use the Millman's theorem in several points of the circuit to get the relations and equations.

But I'm not on my results and I have difficulties to find the equations. That's why I need your advice.

Thank you in advance for your answers.

Best Regards.
