The CNR System® Active uses a humidity-responsive wooden expansion element and a dedicated string action adjustment screw to keep playability consistent across changing conditions. This kit unlocks that system, letting you dial in your preferred setup quickly and accurately without removing the neck or performing traditional saddle work.

Perfect for owners who want to maintain optimal playability year-round or fine-tune for different tunings and playing styles.
