I use an 8-string G6 (GBdegbd'e'). I'm guessing the Cindy Cashdollar one is GBegbd' -you left the 3rd string out?
That Gbdegb tuning is of course standard 6-string C6 down a fourth - it should suit a dobro really well and have a kind of baritonish midrangy sound. Only thing I'd wonder about - it might be too midrangy to be heard clearly in some band contexts. It does seem to be a rule of thumb that the larger and louder your band is, the higher your tuning has to be. In a solo, duo or trio setting it would probably sound really good, otherwise it might be better up or tone or two.[This message was edited by John Kavanagh on 06 November 2002 at 08:45 AM.]
