I've got a set of Velvet Blues that I got in a trade a few months ago. I didn't put them on my bass and they're just sitting around. I would like to trade for either Gut D/G strings (wound or unwound. let me know) or a well used set/singles of Spirocores (any gauge). I'll really trade for anything I haven't tried though so let me know what you have. If these don't go by January 1st I'll be open to the sale of $75. Thanks.
