The range offers a number of different models including Dreadnoughts, 000’s, OM’s, Grand Auditoriums and acoustic basses. Every Sigma has a solid top and there are a number of all-solid models at the higher end of the range. Gloss and satin finishes, along with a stunning array of sunbursts and Fishman electronics make the Sigma range the most comprehensive in today’s acoustic marketplace.
