The Artwood Vintage series now showcases another vintage element by applying an "ageing" process to the tonewood : "Thermo Aged tone wood, made by a special drying process at a high temperature which is commonly known as "baking", "caramelisation", "roasting" or "torrefaction." The Thermo Aged process makes the sound louder across the entire frequency range, especially the bass and treble areas. Having a Thermo Aged solid back brings further enhancement to the sound along with the Thermo Aged solid top; even more bass, even more treble, and plenty of punch. It is a bit like having the guitar 'played in' for years from new! Thermo Aged Spruce bracing further enhances this.
