I am using the medium harp tailpiece since one week. It clearly is better than my former Frirsz one. Response and sound of my Gustave Bernardel has increased a lot and it is a joy to play now. Thanks to Georg to make it possible to get this experience for a fair price. My standpartner Lutz Wagner also is using a tailpiece from you since a week, but a normal one. And he also is happy with it because of the same reasons I told earlier. Thank you and all the best from us members of the Münster Symphony Cello section.
