A tape operator or tape op, also known as a second engineer, is a person who performs menial operations in a recording studio in a similar manner to a tea boy or gopher.[1] They may act as an apprentice or an assistant to a recording engineer and duties can consist of threading audio tape, setting up microphones and stands, configuring MIDI equipment and cables, and sometimes pressing the relevant transport controls on the recorder or digital audio workstation.[2] Abbey Road Studios always assigned at least one tape op to each recording session.[3]
