Pitch Raising

[Farrell]

I know it is not what you want to hear, but it sounds like your strings are
toast. If you are not pulling the string way over pitch accidentally during
tuning, they must just be right at their breaking points. Try splicing your
old strings rather than replacing if money is a problem.
