Aluminum wound over a Perlon core.

“DOMINANT strings are highly flexible, multi-strand synthetic core strings known for their tonal warmth and gut-like feel. They are impervious to changes in humidity, allowing for stable intonation and long life. The sound is soft, clear and rich in overtones. DOMINANT strings, widely recognized as “the reference standard”, are legendary for distinctive tone and playability.” (according to Thomastik-Infeld)
