At the moment I don't offer a money back guarantee, as I will have to book and dedicate the necessary hours to your project. However, there are 2 revisions included with every song. I encourage you to use them to adjust anything that you think might sound better. In the unlikely event that you are still unsatisfied, you can just book extra revision. I would also recommend that you book a call with me prior to start working to discuss any details about your sound and help get it just right.
