The books have two main sections: Models listed A to Z and the much longer, Models listed by year. When researching a certain guitar or amp, I found keeping my place in one section while consulting the other worked well. I also liked that the main innovations or changes from year-to-year are well noted instead of including arcane information most people don't care about.

The included and entertaining DVDs work as a reward and break from reading. Many vintage examples of guitars and amps are shown and played. I found it an excellent lesson for learning the exact differences in all these great instruments. The authors are both guitar players with Verheyen especially adept at many musical playing styles that clearly demonstrates why artists in every musical genre use these guitars and amps.
