What do you need to build a guitar? Here is a basic list of the tools you will need. Tools that made this list are tools that I use on every build OR tools that I have used in the past until I replace them with more expensive tools.
I use far more than 5 tools, but we can break them down into 5 categories. I'm sure we could find a youtube video of Ben Crowe from Crimson Guitars doing a 36-hour build using only a 1-inch gouge.
