A new design from Gotoh with virtually no internal friction. This tremolo will directly retrofit the mounting hole pattern of a vintage tremolo. This bridge can be used to replace a conventional, 6 mounting screw Strat tremolo with very little modification to the body. A small amount of finish and wood may need to be filed off the treble side of the tremolo body route to make way for the round vibrato arm mount that sits under the bridge plate. E to E mounting hole spacing = 56 mm String spacing = 10.8 mm Adjustments for saddle height and locking trem arm into position use a 1.5mm allen wrench which is included.
