Description
Martin DSS Biosphere II, Ebony Fingerboard, Robert Goetzel Art
*This instrument was on display as a demonstration model at the 2025 Winter NAMM show. It has been played and may have slight wear putting it in mint to excellent condition. It has been hand-inspected and setup with any significant playwear listed below in detail. The instrument includes its full factory warranty and original case.*
Dedicated to sustainability and preserving our planet for future generations, Martin Guitar is proud to reinforce that call to action this Earth Day with the all-new DSS Biosphere® II. The third model in their Earth Day series showcases another stunning work of art from acclaimed artist Robert Goetzl, taking us to the waters off the coast of Hawaii. This model is a tribute to the Keiki Kohola Project – Caring for Calves in Maui Waters, a nonprofit that promotes the protection of humpback whale mother and calf pairs during their time in Hawaiian waters. C. F. Martin & Co. has made a generous donation to its cause. The DSS Biosphere II is also FSC® certified, 100% plastic-free, and will be adorned with the Preferred by Nature Hummingbird Seal. It’s a satin sloped-shoulder Dreadnought that provides a warm and mellow tone rounded out by powerful mids, bright and airy trebles, and plenty of volume. All nature has its own song to sing. With the DSS Biosphere II, Martin hopes to raise awareness of protecting the environment, and the beautiful music it creates.
Note: After close inspection, this instrument is free of any major wear, marks and/or blemishes. (See Pics)
We are proud to include a full professional setup to factory spec before delivering your new Martin Guitar. Our world-class techs will dial in your guitar to make sure the playability is maximized on your new Martin!
