  • Guitar vibrato stabilizing device
    Patent number: 9299325
    Abstract: An improved roller assembly that, when installed on a BIGSBY vibrato system, causes the roller to be raised, which reduces the angle of the strings. This reduces the tension on the strings, which improves the performance of the device and reduces or eliminates the instability in tuning. Two versions of the device are disclosed that can be used with both BIGSBY and BIGSBY LICENSE model vibratos.
