Yep. Though ALL tapes are Manufactured..I believe you meant to say COMMERCIAL cassette.
While cassettes are also mastered different than LP or CD, so the higher Harmonic spectrum that digital doesnt Capture is well encoded into the cassette, you might notice though its more compressed sounding too.
Dead air at the beggining and end of a tape is important. The first 20 seconds of a tape are no good.
I think that was an Atlantic Tape so DO check and see if there is the DD Logo on the side of the tape For DOLBY Noise Reduction. (dont remember if It does have Dolby NR or not) ITs the little Square Symbol. That means its encoded with Dolby B Noise Reduction.
Which was desighned to work both ON and Off. Should give you 10Db of boost if your Deck is calibrated right tight.
play the Tape with NR on, and boost up the treble to +6Db (midway around noon) Cut your Bass to 0Db (Dead centre) and you can turn it up real loud, and the Punch of the midrange will do its Job.
