Brilliant! That's helpful. If you get a chance, can you model the effect of the volume pot bypass cap we've been discussing?

Nice work stevek.
Just for clarity, the pspice model is a model of the effect of the tone control only. It's operating as a filter, and the resonant peak position is unchanged, except in the case of tone control set to 0. In all other cases, the highs are being filtered out using the tone control in various positions.
Additionally, changing the volume control on a passive pickup affects the tone by damping the height of the resonant peak, and gives a similar, but less extreme result as the tone control in that the position of the resonant peak is unchanged.
Adding a so-called "volume bypass cap" actually moves the position of the resonant peak.
