From phillip holmes: "...I've been told by collectors and people that were
in the business, that
test pressings were pressed in very low numbers, IE, 100-200 copies for
the musicians, A&R people, producer, big wigs, and the like..."
Those were actually promos. Only four or five real test pressings would be
made. They were used to check the plating quality and then sent to the label
for them to sign off on the production run. An old promo trick was to send
reviewers what appeared to be test pressings which would make them think
they were getting special treatment.
