Finished with a solid spruce soundboard and a preamp and pickup system complete with a built-in tuner, the Sigma Guitars DM12E twelve-string electro-acoustic guitar delivers big sound whether unplugged or amplified. Supported by a mahogany back and sides, the body shapes immediately warm and dynamic tone with just enough emphasis on the trebles to poke through the mix of a full band. The mahogany neck is just a touch wider than a standard six-string model to support twelve-string finger-picking, but is slim enough to support a fast and fluid playing feel. Thoughtful from the headstock to the lower bout, this guitar has been fitted with a bone nut and saddle, a dual-action truss rod and a set of twelve robust mini-tuners to ensure musical sustain, reliable intonation and excellent tuning stability.
