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.
