▪ Amateur luthier Bieber and his professional mentor pursue a new direction in classical guitar bracing that spans 10 guitars over the course of the article. Although Greg Smallman is quoted as an inspiration, the Al-Tho designs look nothing like the lattice system we’ve become familiar with. Nor do they look like anything else seen to date. Very interesting stuff. With 11 photos, 2 diagrams, and 2 charts.
