Do Not Over Tighten.
If you break a string in BALANCED mode, use an alternate tuning,
change string gauge, move the step-stop, and adjust truss rod or action.
Then you will need to recheck to see that the bridge is level (i.e. that the
top of the bridge is aligned with the strings... the HOMEposition).
If you are worried that the bridge is not in the
HOMEposition:
Look at the top of bridge, is it aligned with strings? Peer into the slot in
the backplate. Is the step-stop touching the bridge pin? Push on the heel
of the bridge to see if it is firmly touching the step-stop or is it bumping
it. Look to see if there is excess tension on the spring. Insert the tremolo bar
and with it pointing towards the headstock, try to lift it up. If it moves and
the step-stop is in the HOMEposition, the spring needs to be tightened or
changed to accommodate different string gauge.
General Design and Function:
The bridge pivots on ball bearings. The guitar strings pull the back of the
bridge up toward the headstock. The tremolo spring pushes against the
bridge to level it out.
The two forces match the tremolo when it is balanced and it can be used to
bend down or pull up. If the spring is exerting more force on the bridge, the
tremolo is in
FIXEDposition and the bridge will stay put when left-hand
string bending is employed. If the force of the spring is slightly more than
the string tension and the step-stop is in the
HOMEposition, the bridge is
in BENDDOWNonly mode.
