I don't work for this company, but there is definitely something special about German steel, silver-plated strings. They have a certain richness and brilliance that the more prevalent, Swedish steel, tin-plated (SSTP) strings don't have. To me, they only improve your tone. Just for kicks, I put on some SSTP strings last night, and noticed an audible difference. If you want to try them, you can purchase them here. If you buy a set of these, they are automatically included in the string set. Just some examples above.
