Pirastro Obligato A

Core: Steel
Winding: Chrome steel

The strings are nylon (except for the A string which has a steel core) and adjust well to temperature and humidity, after a couple of days playing in. The sensitivity of the string is slightly similar to that of a gut string.

If the A string of your cello is already quite strong, we recommend  Flexocor as the Obligato A  string would otherwise sound too hard.
