I have designed a simple Electric Guitar SPICE Subcircuit that includes a Signal Generator 440Hz Sine Wave Output at 100mv. The Parameter "440" is the Frequency (440Hz) and the Parameter "100M" is the Voltage (100mv) in the "+ SIN( 0 100M 440 0 0 0 )" line of the Subcircuit and these values can be modiifed to vary the Frequency and Voltage of the Output. The Windings Inductance of the Pickup is 2 Henries (L1), the Pickup DC Resistance is 10,000 Ohms (R1) and the Capacitance is 120 picofarads (C1). Since there are only two connections (+ = 1 and GND = 2) any simple 2 connection Schematic Symbol may be used.

Why would you??? Spice can't do that well at a real simulation, it doesn't have enough variables. IMHO

Paul, which pickup are you modeling?
Dave, I agree there are variables lacking, for instance no one has yet come up with a way to model the change from an A2 magnet to an A5, but Paul's model (which is the same as Terry Down's model*) manages to model volume and tone control changes accurately enough to be useful.
*Note that Terry's model uses a transmission line for the guitar cord, which works to prove his point, but does not work for, say, modeling treble bypass circuits. A simple capacitor does the trick.

PU Model
Well, really my not understanding the point of the model is really the question - maybe I missed something before this post.
I have designed guitar amps, and Pro Audio circuits for years. The variables I'm speaking of are the things manufacturers of pickups and guitars can't even duplicate with todays manufacturing technology. (Ever wonder why say three xyz brand guitars, out of the box, each sound different?)
Additionally, in the case of amplified guitasr, variables such as load, (as you said cable capacitance), Amp/pedal input Z, electro-acoustic feedback, strings age and gauge, pole adjustment...etc. seem to make a model it pretty useless, unless it's for a class project.
I've done my share of PSpice, and other modeling programs - but still I ask - why would you model a pickup?
I'm not trying to bust chops here, just trying to understand the point...
Thanks,
Dave

Unlike amps, the circuits in guitars are very simple, and since the values of available parts tend to jump by factors of 2, the results of changing, say, a tone capacitor, are relatively huge. That is, you don't model a pickup to understand the pickup, but rather to understand volume and tone controls connected to it.
PU Model
Thank You Keriwena,
I see, your not looking at interfacing them electrically so much as an interface, but rather viewing the taper of the volume and tone Fc and slope with a specific PU impedance.Is that the reason?
I am a recovering musician 😎 and I have played with various pots to find smoother controls, quality, etc. I have also played with different tone caps and LC circuits. I never thought about using SPICE for that, as I had a lab full of parts. Something I found interesting was when I loaded Ducan active hot Strat PU's in one of my guitars, is that the tone was a little more manageable due to the fact the pickups are buffered and use twp 9 volt batteries.Since I us a wireless transmitter, I found a voltage divider was required to lower the output voltage swing to prevent transmitter distortion and over-modulation.
Thanks for clearing that up for me....
Let me know what you learn in the endeavor.
Thanks,
Dave

NOTE OF INTEREST: Although this does have ability to simulate a Signal Generated Waveform with Impedance, Volume and Tonal Characteristics, as mentioned by others in this post each Parameter would require slight variation of value to emulate any given actual Electric Guitar. It would be necessary to actually plot the waveform of the guitar sound desired and adjust Parameter Values until satisfactory similar results for SPICE Simulation are obtained.
