Corelli 360M Medium Solo String Set. - Brand: Corelli - Model: 360M - Type: Double Bass Strings - Gauge: Medium (Solo) - Contents: Set of 4 strings - Retail Price: ¥35,000 -------------------------------- Thank you for viewing. ■ Purchased two months ago - only played for 1 or 2 sessions after installation. ■ In my subjective opinion, they feel and are as thin as a softer version of Spirocore Solo. ■ Although the strings haven't fully broken in yet, they give the impression of a thin, piercing sound. ■ There is some curling at the ends as they have been installed once. In this field, it's quite expensive to buy new strings for trial and error... How about trying these? Thank you.
