Specifically, the science behind why some people get better life from nickel strings over stainless, and vice versa? I used to buy GHS bassics strings (nickel plated) because they were $12 at Walmart, but I stopped using them because they went dead on me so much faster than SS roto's and D'addario SS strings. Based on this, I adopted the stance that I must play stainless strings over nickel if I wanted the strings to retain any brightness at all. But I'm wondering about a couple things: 1) Will I neccessarily have the same bad luck with any nickel plated string? Or are Bassics just crappy strings? 2) Is the deadness I'm experiencing coming from the material itself (in this case nickel), or is it because of the thin plating? For instance, would I have the same trouble with a gold plated string? I ask because if the problem is the plating, I may be able to try some of these alloy strings. They have nickel blended with stainless in the outer wrap, but they aren't plated in a thin layer of nickel, at least that's my understanding. So, if anyone understands the science, please chime in. Is it a ph issue? Acidic/Alkaline? Or it more to do with oil content in skin? And if you can, tell me, what can be done to counteract it, if anything? I'd like to try Circle K strings, and the new D'addario balanced sets, but don't want to waste the money if I'm going to have the same issues that I did with Bassics.
