Add knobs to your grid with this add-on accessory for the UNTZtrument. This is a replacement piece of laser cut acrylic to use when building an Adafruit UNTZtrument. It's perfect for adding a rotary encoder or any of our panel mount potentiometers.

Swap this in during your build or upgrade your UNTZtrument after the fact. This piece can be used for any/all of the sides except for the one with the USB cutout. So you can use up to 3 for left/front/right knobbin' action.
