Brand new nanoRings built by an electronics engineer with over ten years of experience. Identical to a factory Mutable Instruments Rings, in only 8 HP! The panel on this module is manufactured by Magpie Modular, makers of some of the highest quality panels in Eurorack. It is white aluminum with a beautiful textured finish. Calibrated and tested, with factory Rings firmware. Ships promptly with a Eurorack power ribbon and some bonus treats. All our builds come with a one-year warranty, so we stand behind the quality and durability of our modules.
