The rosette on an acoustic guitar, along with the peghead and bridge designs, is a big part of the custom builder’s signature. Often a particular design will immediately identify the guitar as being made by a specific individual. Perhaps the amazing artwork created by Ervin Somogyi is the most extreme example among contemporary luthiers. I favor a more traditional, old school approach to design and yet I am drawn to using unusual woods in an artistic way. I am especially drawn to spalted woods, and I have some in my stash that dates back to 1983. The pictorial gallery below shows some of the elements involved with designing and building a segmented rosette using spalted Maple.
