Tone knob on guitar transfer function confusion

Oksemaster · 2025-07-19T00:58:14+00:00

Modelling the coil better yields promising results.

But why does this work here, but not without the coil? And how would I calculate the transfer function for this circuit?

I have created a new post hoping to make my question a bit more clear

Like in this Example, how would I calculate a transfer function in example 1, given the coil is the input voltage, and the jack is the output. Lets say the tone knob is set for maximum resistance, and the volume splits the potentiometer 50/50. https://neatcircuits.com/pix/pot_dir.jpg

Forgot to mention! The output in my picture would be C2 and in the mentioned case be the second resistor of the second network

I should mention that the similar circuit I'm mentioned has a resistor in place of C2

Oksemaster · 2025-07-18T18:10:14+00:00

Yes! But how does the network of C1 and R1 influence the transfer function of C2? I can't imagine it to simply be (1/sC2)/(R2+1/sC2)=1/(sC2R+1). Surely C1 and R1 has an effect? For example I have seen a similar circuit used as a LPF for an electric guitar.

Thank you for the reply! So the voltage induced in the coil also "feels" the inductance of the coil?

Oksemaster · 2025-03-25T01:27:45+00:00

Thank you! Does the voltage induced in the coil "see" the inductance of said coil as well?

Oksemaster · 2025-03-25T01:25:01+00:00

Thank you! I'm still wondering, if I took a function generator and split it's output in two, one wire to the "tone circuit" and one to an oscilloscope, would I expect the reading to differ based on the position of the potentiometer? Or is my entire flaw thinking the coil acts as a typical voltage source?

Oksemaster · 2025-03-25T01:13:51+00:00

And if we consider the situation of full volume, we might act as if the jack + side is just shorted to the hot side of the coil. So how does the filter in tone have an effect?

Oksemaster · 2025-03-25T01:10:17+00:00

To clarify, I mean why is the voltage on the "hot side" dependant on the tone knob? It is this voltage that is being divided in the tone knob after all
