Lee Sklar plays a lot of Dingwall, Also with the current Toto tour
I played the D-Bird last week at The London Bass Guitar Show. It was made for Dutch guy Rob van der Loo. He asked for the shape. It's really nice, the headstock echo's the Tbird headstock a bit. The body is even thinner at the edges as a real Bird.
Sheldon Dingwall is a great guy btw.
