I am a beginner Bass player, bluegrass only. I have a 1963 Kay M1, nice bass. But I'm not liking the strings, been thinking about changing them, but the cost makes it a bit hard to experement. Does anyone know anything about the, Black Diamond Dog House Bass strings. They are supposed to be especially for Bluegrass playing. So far I can't find anyone using them.
Also, if I should change strings, does anyone buy used strings, they are only a couple months old?
Thanks for any help you may be able to give.

I put some Supernyls (the older nylon stand-bys) on a friends bass who is also a beginner. They seemed perfect for learning. I've also heard several bass players over the years, who play infrequently, say they avoid steel strings, but gladly pickup someones bass if it has nylon on it. Perhaps someone could comment on the cheaper nylon strings on the market now?
