Are they nickel or SS strings?
I was thinking about getting a set of red ones for my cherryburst NS20005 but the strings that came on it are ok so I haven't done it yet.
I believe they're nickel with a round core, basically Sunbeams with the K3 coating. So far I really like them, and I've heard they last a long time.
They are nickel for sure.
I think evanatch is correct they are basically Sunbeams with the K3 coating.
