Based on my playing style and goals for the 00-12, Michael chose a top set European Alpine Spruce (Picea abies) from Graubünden region of Switzerland that came to him from Florinett AG, Tonewood Switzerland (

Here are some solid Spanish Cedar linings being fabricated to conform to the 3-dimensional tapered rims and being installed to the Koa sides.
Michael made a beautiful, simple Koa rosette using his hot sand shading of the rosette segments. You can get a sense of the contrast and figure when solvent is wiped on.
