Unique voicing process
The premium nature of the Rainbow Gc-KR is underscored by the fact that both the soundboard and the back plate are individually tuned using the voicing process, our proprietary technology that enhances the guitar’s tonal properties to the highest level. Thanks to that, the Rainbow Gc-KR has a crystalline clear, harmonically rich, balanced, and highly dynamic sound across the entire tonal spectrum.
Full-Pore Finish
Full-pore finishes are characterized by their smooth surface, which protects the instrument and at the same time increases its attractiveness. However, when developing our finish, it was not enough for us to achieve only excellent protective and aesthetic functions. We focused our attention mainly on its resonant properties, which are significantly influenced by the composition, thickness and method of applying the lacquer. We have thus created a unique high-resonance coating for our instruments and the associated advanced methods of its application.
Our full-pore finish consists of an ultra-thin layer composed of up to ten individual sprays. Thanks to its UV-based composition, it is extremely hard and transfers sound perfectly. At the same time, it is very durable and maintains its crystal clarity for a long time. In short, an acoustic lacquer for the 21st century.
We divide its final processing into three categories: High-Gloss Finish, Vintage Finish and Satin Finish.
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.
