You may be talking about the D'Addario brand folk guitar string with a thickness of 0.019 inches. This string is typically used for the high E (thinnest) string on an acoustic folk guitar.

It is important to note that string tension and tone depend on several factors, such as string length, guitar pitch, playing technique and personal preference. It is therefore possible that other brands or models of folk guitar strings with the same thickness may have different sound characteristics.
