Someone shared this on another forum a month ago.

It is a good (and also free) resource about how guitar and guitar electronics work from a scientific point of view (yes, there's math in there). I read some chapters and it is really interesting.

The theory section also includes some great info too: http://www.guitarscience.net/theory.htm
