Roger Yang is a self-taught luthier, who has been building concert classical guitars since 2007. Prior to that he was in the import-export business of fine woods for more than 20 years. As part of that business he began importing fine Spanish guitars, including a Ramirez Centenario guitar. His business took him to Vietnam, and finding an abundance of suitable woods for guitar building there, with two friends in 1990 he set up a guitar factory (Emotion Instrument company, which is now the “Ayers” brand). He was put in charge of technical development and international marketing, and attended major instrument fairs (USA / Germany / Japan). These experiences brought him into contact with many of leading luthiers in the world, and taught him the fine points of material selection and guitar making. A long time audio-file, Yang brings a profound knowledge of loud-speaker design into his guitar making. His knowledge and understanding of acoustics has paid big dividends. His guitars are beginning to win international prizes at the 2014 (August) Taiwan International Guitar Festival and Competition as well as at 2014(October) Germany Berlin Guitar Festival and Competition.
