The music Tool creates leaves in its wake a long list of unanswered (yet
answerable) questions. In 1994, the Tool FAQ was born, designed to keep people
from having to ask the same questions over and over.
But over the years, the FAQ became less about giving answers to people who weren't willing to do a little work on their own, and more about being a starting point for people on their quests for personal enlightenment (vis a vis Tool, that is; let's not lose sight of ourselves here).
Enjoy your journey. The FAQ is free to distribute as long as it is unmodified.
It has not been updated since 2001. It is unclear if it will be again, or indeed if there is even a need for an update, given the many other sources available online now. Perhaps its time is past, and it survives best as a primary source for Tool info up to 2001.
