I use these strings for about two and a half months and they correspond in every respect to my standards. playing comfort rather stunning, perfect tension, or "cheese grater" or "soap", less noisy than many other, great sound, whatever the technique used, no significant fatigue after several hours of gameplay, perfect tonal balance , a tone that "twist" not my eardrums ... Who's "charm" rather ...
A simplified installation by just a length of string to the note ... No need dedicated cutters.
on the other hand, they will not be suitable for bass players with a big "attack" or seeking a strong "presence" in the middle of the spectrum, without having to touch the "Equal" ... I do not think, either, that this type of string is suitable for lutheries made of mahogany or species that is analogous. A check ...
A pulling equal, I really had to try a dozen games before it.
No loss of definition, so far .. To be continued
Quality / price ratio good for me.
I do it again this choice in a heartbeat.
