For over 15 years Grandi Liutai Italiani has been perfecting the art of selecting, cutting and drying timber, in particular the Bosnian Sycamore Maple. The work and suggestions of many violin-makers moved the production to a completely innovative approach in all the bridges. Standard models include violin (2 models) and cello (2 models). The passion for the craft and the rigid quality control procedures in GLI have resulted in all bridges being very well recognized by restorers and makers in high-grade bridges. Taking as an example the violin bridge, GLI customers will find in both models two very important solutions to the many problems with which they are regularly faced: The semi-finished model (need only the finishing/final touches of the instrument maker) and the full model, highly customizable for a multitude of shapes. All GLI models have machine/precision cut, harmonious curves. The thicknesses of the top and feet of all GLI bridges are generously proportioned to give the maximum freedom in final shaping. We believe that the bridge is a combination of different elements, that contribute to create a perfect transmission of the sound from the strings to the violin. Indeed the main job of the bridge should be transferring some frequencies whilst damping others at least partially. Every good violin-makers know how to carve the shape of the bridge to emphasize the quality of the instruments. Below the kidneys there is a horizontal bar working as a spring in fact. The actual design of the bridges can work perfectly only if the wood is very hard. We noticed that increasing the stiffness with our personal treatment, the carved parts should be applied just for weight reducing. This is the reason why we decided to treat the wood of all our bridges to increase substantially the resistance and the density of the wood and let the maker to create his ideal work.
