Minoru Kimoto of Yamamoto Strings (Tokyo, Japan) has send me a YouTube link of double bassist Yoshi Utumei, playing arco on Presto Jazzicato Tungsten strings.
The Presto Jazzicato string has a steel core with black nylon wrapping. We (the Presto staff and I) designed the Jazzicato strings primarily as a (Jazz-) pizzicato string. But Yoshi’s performance shows that they are a fantastic orchestral arco string, too! Yoshi’s tone has a nice, cello-like timbre, but doesn’t lack the deep fundamental bass.
In comparison, the Jazzicatos’ tension is already low, and putting them on a 1/2 size bass lowers the tension even more (due to the shorter string length). I guess his bass is pretty easy to play.
