Fender 400 (1964) lowering screw disengaged.

The black screw that should set the amount of lower on my second string is totally disengaged. I can turn it full travel from left all the way to tight, and it does not affect the string travel one bit. The string should lower from C# to B, but it goes a few cents too far. I can not see the screw when I look up under. Just the springs and som brass-like tubes. What to do?

Check the tension on the cable. At times you have to mess a bit with the cables to get things working well.

What Russ said - sounds like the turnbuckle is a hair too tight. Loosen it a bit, re tune the guitar and then start over. That almost always solves it.

Terje, if the screw indeed does stop, that proves it's still engaged in the threads of the loop inside the changer. The loops in the changer that limit string travel are quite similar to those under the guitar (that the cables hook to), except that they are reversed, and have the tuning screws threaded into the brass tubing ferrules.

The proper adjustment for the cable turnbuckles is to loosen them until the cable is slack, and then re-tighten them until the pulling finger they hook to (under the guitar) just barely starts to move, and then back off (loosen) the turnbuckle 1/4 turn.
