Furch CNR System

Given that the neck is one of the most important components of a guitar, devising a neck design offering maximum stability has been a great challenge throughout the history of guitar building. Following many years of research and development, we are proud to introduce the Furch CNR System (Composite Neck Reinforcement), a revolutionary neck design that relies on state-of-the-art materials to bring unmatched stability thanks to which the neck has 90% higher resistance to deformations caused by string tension and changes in humidity compared to traditional neck designs.

The Furch CNR System consists of an adjustable truss rod placed inside a carbon casing. Combined with a high-precision manufacturing process, the innovative design translates into unparalleled stability of the neck joint and the neck along its entire length as well as supreme accuracy of neck relief adjustment. Because it is very rigid, the neck joint of Furch guitars does not need heavy reinforcements, which makes it much lighter than traditional designs. In addition, the absence of reinforcing components allows a larger area of the soundboard to resonate freely and produce better sound. All parts of the Furch CNR System are invisibly integrated into the neck.


  1. A fully adjustable dual-action truss rod for highly precise adjustment of the neck bow in both the convex and concave directions.
  2. A highly rigid carbon casing that maintains the neck in the set position over a period much longer than is the case with standard neck joint designs and, at the same time, facilitates a gradual bow in the neck, a factor of essential importance for playability.
  3. A casting made of special alloy located inside the neck heel that ensures a stable position of the neck and its angle vis-à-vis the body.


The Furch CNR System neck joint design is available in all Furch guitars with serial number 68,294 and higher.
