As gravitational waves are now being nearly routinely measured with
interferometers, the question of using them to probe new physics becomes
increasingly legitimate. In this article, we rely on a well established
framework to investigate how the complex frequencies of quasinormal modes are
affected by different models. The tendencies are explicitly shown, for both the
pulsation and the damping rate. This opportunity is also taken to derive the
Regge-Wheeler equation for general static and spherically symmetric metrics.
