Lacquer Disk Cutting
This is the process by which your audio gets cut into grooves on a lacquer disk. Our Scully lathe is controlled by a complex feed amplifier circuit. This feature controls the distance between the grooves to insure that no space is wasted (causing a lower level on your disk) or that the grooves do not overcut one another (causing a skip). This lacquer master disk will ultimately become the metal stamper that is put into production to make your vinyl records. This process will give you a clear and defined finished pressing.
We can also cut a 7”, 10”, or 12” playable record for you. Unlike masters, these lacquers (known as acetates) are meant for listening back,
ensuring that your music translates to the vinyl medium properly.
