I avoid playing my Fender Stratocaster on stage because of the ever present possibility of breaking a string midstream while playing. Anyone who has a guitar with a floating tremolo system knows that once you break a string, all of the other strings go out of tune. I know many guitarists keep more than one guitar handy on stage. I have heard of others who have "blocked" the floating tremolo to cure the problem. I am interested to learn how many of you deal with this problem.
