Sigma acoustic guitars have been C.F. Martin's import brand since 1970. They mirror most of their American models. This model, the SD28-CE has a solid sitka spruce top and a Rosewood back and sides. The forward X braces are scalloped and shaped by hand for a more responsive sounboard. Whether you pick, finger-pick or strum this guitar will respond to your style. The mahogany neck has a satin finish and feels smooth and not sticky. A real bone nut and saddle will create a natural tone like the big brother Martins. Also, the hand fitted dove tail neck joint will add to the sustain you will need for a great performance. This guitar has a nice big warm sound with strong mids to acommadate lead lines and that hook you want to come through the mix. Also to help out is the powerful B-Band pre-amp system with EQ and built-in tuner. All in all, this Sigma guitar is a very good buy.
