• When "SOL", "SO", or "SON" appears in the runout grooves of a release issued prior to ca. 1975 that was manufactured by another pressing plant, it often indicates that Sonic made metal parts used to manufacture the record.
• The presence of "GOL" in conjunction with any of the identifiers listed above indicates it was pressed by Goldisc Recording Products, Inc. sometime after ca. 1975 and that Sonic manufactured metal parts used to manufacture the record.
