Jack White doesn’t always do what he says he is doing…drives audiophiles nuts
To finish, hopefully, if you gave me a choice between owning the master tapes or a test pressing I would take the tapes any day but the master tapes are incredibly rare.
Many tapes were destroyed in a Cali fire so they don’t exist…many were lost over time
But I really don’t think record companies made a habit of sending copies of master tapes
