These are D'Addario EJ44 Pro Arte Extra Hard Tension Classical Guitar Strings Just over two years old !
This guitar never sounded as good with these as it does with regular tension. Probably too tight for her to ring fully, slower bass response for rasgueado etc.... I honestly don't notice any extra tension as it's a really nice guitar to play with them on.
I guess this is a repost but it was buried in another thread so I hope you don't mind. I put it up the other afternoon because Maggie actually wanted me to play for her, it was fun and summer is coming.
In another month or so I am actually going to put on new strings. I'll let you know how she sounds, should be a bit better.
