Hi All,
I’m posting this in both the Guitar Tech and Pickup Makers sections.
Here are two Excel worksheets I developed to model the frequency response of a pickup installed in a guitar and plugged into an amp. These are one-trick ponies, not all-purpose circuit simulators. You plug in the pickup’s DCR and inductance, the tone cap, volume & tone pot values and settings, cable capacitance, and amp input resistance – and Excel (almost) instantaneously generates plots of output amplitude & phase vs. frequency.
It would be a relatively simple matter to expand these worksheets to model a 2-pickup “Les Paul, ES-335, etc.” configuration. But I am not likely to do that until I personally need such a tool. If you want to, have at it.
I used to use NI MultiSim for this kind of thing, but ran out of ways of sneaking around the 30-day free trial period. Can anyone recommend another free circuit simulator with relatively easy learning curve?
Thanks,
