The richness in overtones is closely related to the position of the threads which are squeezed in between bridge and strings. The position of the threads changes the bearing angle between strings and bridge and so influences a strong or less strong vibrating/twanging which is responsible for the richness in overtones. If you would like to maintain or change the richness in overtones, you should newly adjust these threads every once in a while in order to keep your favourite sound pattern. This may be necessary with every new tuning of the instrument. Your satisfaction is our priority. We want you to be 100% satisfied with our products and our service.
