If you have a school that specializes in archtop construction, JUMP at it. This type of school will more than likely teach you in a traditional Cremonese and Barcelonian styles which will actually teach you Luthiery and not just "guitar building". There is a vast difference between a trained luthier and a guitar builder. If you wish to learn to be a luthier, school will introduce you to traditional construction and understanding of luthierie and put you years ahead of a guitar builder as far as knowledge and applicable skills in the marketplace if you wish to go to work for a high end company such as Griffin, Breedlove, or Taylor. Martin, Gibson, Fender, and G&L also hire out of school placement programs. Knowledge of machines and tools is also a great help in excelling as a builder.
