In 2012 I initiated a research project focusing on measuring and analyzing a historical guitar by Antonio de Torres (built 1864). The results from this research are not yet ready for publishing, but a very short preview is available on my youtube channel. Watch the demo video below or check it out directly on YouTube.
The video below cycles through each layer of the FE18, which gives quite a bit of insight into the material decisions Antonio de Torres made for this instrument. Repairs and patches also become nicely visible.
