I bought these strings at least a year ago, if not a little longer ago than that. Cordelia (my Cordoba C-5 classical) needed re-stringing then. Well, Sweetwater's amazing promptness and customer service aside, I did not get around to it...I just putting it off and putting it off and putting it off.
Well, today, I finished excuses and changed my strings.
So, now my girl has a lovely voice again...she's no longer off-sounding, even in tune.
