An improved tremolo and tuning apparatus for stringed musical instruments is disclosed which presents a relatively low profile when mounted on the stringed musical instrument, and yet possesses string locking and fine tuning capabilities.

A rotatable string support block for each of the strings is rotatably mounted on the base plate so as to provide a string support area above the support surface of the tremolo. A string clamp is connected to each of the rotatable string support blocks for holding each of the strings relative to the rotatable string support block. A pivot arm is connected to each of the rotatable string support blocks and includes an extended portion which is at an elevation below the support surface of the base plate when the tremolo is mounted on the stringed musical instrument. Adjustment members are mounted on the tremolo and are engageable with the extended portions of the pivot arms for rotating the rotatable string support blocks and associated string clamps as a unit so a…
