I have a Gamut copper wound, medium gauge E and A string for sale.
They were on my bass for about 3 days and sealed in their packaging since then. These are handmade, loud, excellent strings. From the Gamut website (http://www.gamutstrings.com/catalog.html?Vl=4&Tp=2):
A string list price: $124.59
E string list price: $148.29
I will sell both of these for $200, shipping included.
