How to identify M&S mastering:
Usually Tom Meyer is credited on the release itself.
Please use "Mastered At - Master & Servant" & "Mastered By - Tom Meyer (+ANV)"

How to identify M&S job IDs in the vinyl runouts:
1993 - 2003: M&S (often in combination with SST Brüggemann GmbH and/or Optimal Media engineer signatures and/or job IDs - credit companies and engineers accordingly)
2003 - today: YMS #### (e.g. YMS 1600) - the 4 digits represent a unique, sequential order number, assigned by M&S to their own vinyl productions and can be added as LCCN number (often in combination with Optimal engineer signatures, job IDs and/or geometric plating markers - credit companies and engineers accordingly).

Please use "Manufactured By - Master & Servant" or "Manufactured By - Master & Servant YMS ####"

In general all cutting and pressing is outsourced to Optimal Media GmbH, unless a customer chooses their own cutting studio.
