Just picked up a dr 28, which looks nearly new except for the nice colour and patina. Put new strings on it and wow, I'm amazed at the sound. Now I always thought that all Sigma's were laminate back and sides, but if I look very carefully and follow the grain pattern inside to out all around the sides and back, it matches the outside. This would make me think solid, but I was under the understanding they were laminate. Does anyone know if they grain matched the inside and outside of their laminates?
