More or less the standard for Perlon-core strings. The wound-E string is much less shrill than a plain E can be on many instruments, especially fiddles with a low string height. 4/4 size.
This strings are great for electric as well as acoustic violins and fiddles.
E (steel core aluminum wound)
A (Perlon core alumimum wound)
D (Perlon core alumimum wound)
G (Perlon core silver wound)
