Flamed maple
Botanic name: Acer pseudoplatanus
Origin: Austria, Switzerland, Scottland
Properties: Sweet singing tone with rich mids, not too much bass and subtle trebles
Flamed maple is basically a 'normal' kind of maple. The so-called flames are caused by the weight of the tree itself. In the years of growth the lower log sections get compressed, which makes the fibers grow wavy. Those waves produce the flames in the eye of the beholder.
