  • We can usually turn mixes around within 2 weeks, but if we can’t we will let you know and you can decide whether to proceed or receive a full refund.
  • If you have a deadline, let us know in the form above and we will let you know if we can make it – if we can’t you can decide whether to proceed or receive a full refund.
  • There is a ceiling that we can achieve in the case that a poor recording or production idea hinders the mix.  We will let you know before starting work if this is the case and you can decide not to proceed with a full refund provided.
  • We can add re-amping / new instruments / new ideas into your production if you like – just contact us to find out how much extra that might be.
  • The files we provide are at 24 bit mix level (ready for mastering) and also at finalised mastered level.  We do not charge extra to provide the ‘mastered’ version, so you can confidently go to release with these files immediately.
