This is a new build of a micro version of Rings from Mutable Instruments. MicroRings, also called NanoRings, retains all the same functionality as a full-size Rings module.
These modules use tall bushing potentiometers to offer a more stable feel. You can see the difference in the last picture. You will feel much less wiggle with the tall bushing (left) than with traditional trimmer style (right).
The module is fully assembled, tested, and calibrated. Eurorack power cable is included.
