Dark Series for Grandmother strikes the perfect balance between classic and modern, featuring an all-black aesthetic that invokes the timeless look of early Moog modular systems—with all the functionality and versatility these two state-of-the-art sound design machines are known for. Grandmother's circuits, spirit, and analog effects is inspired by the classic Moog modular synthesizers designed by Bob Moog during the '60s and '70s.  The instrument quickly became a staple in studio setups and live performance settings, a go-to first synthesizer for beginners, and a multifaceted creative tool used by musicians of all skill levels to explore the power of analog sound.  A complement to the distinct multi-colored artwork of the original Grandmother synthesizers, Dark Series presents a style option that celebrates the intersection of tradition and innovation.
