When stringing the guitar and just tuning you can already hear that these strings sound very nice. When playing chords they sound very clear and full, they also feel nice to play.
But..
This only last for a few days, and I didn't even play that much on them. Which is a shame really, as these are not ¤5 strings/set.
If they lasted a little longer, they would be amazing strings. They are nice for experimenting with different string materials, but unless you are a millionare who can afford a new set everyday, they will be just that.
