Treble Gut (Beef Serosa; Academie)
All Gamut Academie strings (pure gut and gut/metal-wound) are made with beef serosa unless they specifically say “sheep gut.” All pure gut Tricolore violin and viola strings are made with sheep gut; gut/metal-wound Tricolore and all Red Diamond strings are made with beef serosa.
Gamut Academie strings are designed for Baroque instruments by those musicians playing historical performance practice at a=415, and are perfectly suitable for modern a=440 practice, but the result will be a little bit more tension at a=440.
This is another variety of treble gut. The serosa from which it is made comes from cattle from the green fields of Ireland and has a higher tensile strength than does sheep gut. Like the sheep treble string, the beef treble string also has a twist angle of about 15º, and this construction gives it the strength and resistance it needs to stand the strain in the treble register.
This type of string is characterized by a low twist that is sometimes not even visible and the color of the string ranges from clear to white. Because beef gut strings are stronger than sheep gut strings they are a good choice for instruments with a long string length, or higher tension situations.
Beef serosa has a higher tensile strength than does sheep gut, so this string is useful for instruments that require extra durability. If your instrument has a longer string length which puts it beyond the comfortable range for sheep gut strings, the beef gut would be a good choice for string selection as it will stand the strain a little better.
