I'm trying to model a circuit. Part of this circuit is a guitar amplifier. I don't know what kind of circuitry is inside the guitar amp, it manufactures often list the input impedance in the product specifications.
When they say input impedance, do they mean the impedance between the signal input and the ground? Can I simply treat the input impedance as a resistor?
