D'Addario NYL020W Classical Guitar .020, single string

It’s a very good bulk string. Purchased them to make a custom set on a requinto and alto guitar. I didn’t like the individual string tensions of packaged sets, including D’addario. That said, Hannabach strings are superior in sound and resilience. The Hannabach trebles have more body or roundness in tone. The D’addario .022 nylon string snapped the first time I tuned it up, the Hannabach lasted at least 1 year plus without any problems. Unfortunately, Hannabach doesn’t sell individual strings.

Purchased a set of these strings to tune a concert ukulele like a mandolin. Strings E-018, A-027, D- 020W, G-030W. Took a few days to get the strings settled but I now have a mellow "mandulele" to easily jump to from mandolin.
