@@Ricky48888 Jack is a good recording engineer so they can try different ideas efficiently and find what works. She's listening to the music and telling him what she wants for adjustments, She isn't thinking about dials and knobs, levels and levers. He does that. . If she was alone in the studio it would take all day to accomplish as much work as they can do together in an hour, I doubt Jack's ever said, "no" to a suggestion she makes.

Indeed

He Has accomplished more than you
