This is an awesome playing hard rubber Slant Signature Berg Larsen for Alto. The piece was originally marked 75/3 with the offset SMS, and measured out right at .069". We sent it off to Erik Greiffenhagen to work his magic because it was a little stuffy in the mid register. He opened the piece up to .082", and now it has that brilliant hard rubber Berg alto sound that so many players long for. Think Dick Oatts!!! This is a great example of what a vintage Slant Berg should play like. It does have some scratching on the back of the barrel from a previous ligature.
