Filtering the entry title in Wordpress, using Genesis Framework

For the life of me, I can not get this to work! All I need to do is filter the entry title/ post title to change the class from "entry-title" to something else.

I am using the Genesis Framework, if that changes the way it has to be written.

One thing to note ... I am looking to change this on the archive pages, so the entry-title needs to keep the permalink wrapper.

Can I get a little help? Cheers!
