The "Boston Herald" revealed that country music stars Faith Hill and Tim McGraw have both said they are using Auto-Tune in performance. They said it is a safety net that guarantees a good performance. Sara Evans, John Michael Montgomery and Gary LeVox of the group Rascal Flatts also use Auto-Tune to fix pitch problems. However, other country music singers, such as Loretta Lynn, Allison Moorer, Trisha Yearwood, Vince Gill, Garth Brooks, Martina McBride, and Patty Loveless, have refused to use Auto-Tune.
