I AM IMPRESSED!
I am not easily impress by strings, but this particular brand certainly has. As mentioned by others, these are round core strings, so please follow the instructions and not cut them until they are on. The tone is warm, not bright and thin sounding like other, and they break in very nicely. I guess if I had to compare them to another branch, it would have to be Newtone strings. They have simular characteristics. So far, for my Gibson J-45, these seem to best string I have tried (tried Martin LifeSpan, Elixir Nanowebs, GHS Laurence Jubers, D'Addario EXP's all in the past 2 months). So, needless to say, I will be stocking up on these and I would recommend them in a heartbeat!
ProsThe feel, they seem to have lower tension that other brands. I used medium gauge (13-15) and they feel like light gauge. Oh, and yes, let's not forget the sound!!!
ConsNothing so far.
