A locking and tuning stabilizing device for an electric guitar having a tremolo
device includes a clamp screw and an adjustment screw to enable the player to lock
the tremolo or to stabilizing the tuning of the strings by turning an appropriate,
easily accessible knob projecting from the guitar. In a first embodiment, an axially
movable pin is in contact with the tremolo device at one end and in contact with
an adjustment screw disposed in the end of the guitar at the opposite end. In second
and third embodiments, an anchor block is disposed within a cavity on the back
of the guitar. A pin connects to the tremolo device and is axially slidable within
the anchor block. Clamping the pin to a fixed position within the anchor block,
by tightening a clamp screw disposed in the anchor block, functions to lock the
tremolo device in place.
