Custom record mastering and pressing facility in Hollywood, California (USA), founded in 1957 by Custom Fidelity Records.

The company was specialized in short-run high quality pressings, mostly for local colleges and small firms. In 1967 a professional audio equipment sales division was formed that catered to studios across the country. In 1970 a special products group was formed to package oldies for radio stations. (This was intended to provide more business during the non-school months.)

Identifying marks are an etched CF or a stamped logo (see pictures) in the runouts. Pressing ring size is 73mm (1962-1975).

In the early 1970s a new mastering process was introduced, using a Neumann VMS-70 computerized lathe with Neumann SX-68 cutterhead and amplifier for tape-to-disc transfer.
