Since the mid-sixtees Robert has been a fan of the accordion. As an orchestra player, conductor and instructor, he has studied the structure and possibilities of the accordion. Through vocational training and practice in precision engineering and electronics, the skills to repair and modify the instrument were born. Robert is active as a player and as an experienced supporter in the Accordionclub Wehr (DE 79664 Wehr). Since then, all problem cases in the orchestra and requests for extra equipment have been completed in-house. Now the focus is on the development, production and distribution of AKKOtune Tuning Tables.
