What Grapehouse Studios will deliver to you:

If that should be the case, you will be informed, so you can have the option to cancel the job and receive a refund.


- One revision is included in the price. Please ensure to inform Grapehouse studios within 24 hours of mix delivery if you require a revision. Later and more enquiries will be charged as a new Mastering job.

Our definition of a revision is a reasonable number of minor tweaks to levels or Equalizing elements in the mix, e.g “bring the overall brigthness of the the track up or down” or “add more boom to the entire track”. “Make more overall compression” Major changes in direction will not be accepted as a revision, and will be treated as a new job. This is why we strongly encourage clients to provide as much written instruction as possible, along with a commercially released reference song.
