The Sigma DMRC-1STE is a new electro-acoustic coming in October 2015. Like the DMC-1STE, the DMRC-1STE features a solid sitka spruce top, but Sigma have opted to use rosewood instead of mahogany for the back and sides. This gives it a different sound, some players prefer rosewood over mahogany- now you have the choice! Other features include Fishman Isys + electronics, a bone nut and a satin mahogany neck.
