ABSTRACT:
A guitar tremolo stabilizing device is disclosed. The stabilizing device is comprised of a base member having a ring-shaped member slidingly attached thereto. One end of the ring-shaped member is attached to a connecting rod which is biased by a compression spring. The opposite end of the ring-shaped member is attached to a section of roller chain which, in turn, is connected to the bridge for a tremolo arm. In the normal operating position of the device, a "pre-load" is applied to the spring causing the ring-shaped member to contact a stop member preventing any lateral movement therebetween, and the section of roller chain is taut. When it is desired to lower the "pitch" of the guitar, the bridge and lever arm are rotated in a first direction causing the ring-shaped member to move laterally with respect to the base member resulting in further compression of the spring while the roller chain section remains taut. If it is desired to increase the "pitch" of the guitar, the bridge and lever arm are rotated in a second direction causing the ring-shaped member to move laterally and contact the stop member preventing any further lateral movement therebetween and causing further compression of the spring while the roller chain section becomes "kinked". If a guitar string breaks, the ring-shaped member moves laterally with respect to the base member and contacts the stop member preventing any further lateral movement therebetween, resulting in the tremolo returning to its tuned state causing the remaining unbroken guitar strings to remain "in tune".
