It's been extremely hot here in Italy this last month and I've been doing a lot of outdoor concerts with high temperatures and very high humidity, which is really very difficult to play. It seems to me that my Chorda Carlos Henriquez, the G and the D, are ruined because of this. Over the last month they have become very rough, wrinkled, they have started to lose some "hairs" (which didn't happen before) that I cut with a nail clipper. I lubricate them with almond oil every ten days or so, but now they suddenly seem very deteriorated. Is it possible that it was the intense heat and the truly unbearable humidity? Has anyone had the same experience? What to do? I've been playing this set for two and a half years...
