Trust me. He knows what he is doing. You might want to consider it. He doesn't charge much either." Dr. Al Sanderson is the inventor of the Sight O Tuner and the Accutuner. We in PTG have been blessed with his interest in piano tuning, as well as his membership in the guild, as he was/is a professor of physics at MIT (?). It was he who pioneered the graphing of what a proper piano tuning looked like. So many of us owe so much to this man who has probably single-handedly contributed more to our profession and livelihood than has been properly acknowleged. Carol Beigel, RPT Greenbelt, Maryland
