Sigma guitars produce a series of classic Dreadnough instruments that closely resemble the design look and feel of the most successful and historically important of all guitar builders, and that is of course the Martin guitar company. This Sigma DR 28 has so much Martin DNA buzzing though its veins that it will be very familiar to any player who is used to the classic D 28 design. Sigma have gone to great lengths to get every aspect of this ranges construction and design to blend perfectly and as a result the DR 28 has a balance and feel that performs in a simple and elegant fashion and will appeal to any player of any ability and experience.
