I was in Nashville this week, and stopped in at Gruhn Guitars. They had a Tobias six string previously owned by Willy Weeks, for $2000.00. It was a very nice bass, but I can't find a comparable one on EBay to gauge a value. The bass did not have a serial number on the back of the headstock, but the salesman did say it had a number, and it was a Gibson style number that would date it around 2004. I did play this bass, and it is a good one. I just don't know what the going price for this model is. Thanks for your help. BTW, also looked at a Roscoe six string, and it has my eye, big time.
