Does Dream On - Aerosmith have reverb tape delay return rather than send?

This brilliant song was accidentally listened too while batteries were going very weak on a Sanyo MR-410 cassette tape recorder.


Tape speed was down, pitch was down a few semitones. Delay on the vocal could be more clearly heard.


(By the way was the voice recorded at a bit lower speed for the well known varispeed effect to get this out of ordinary world voice quality at normal tape speed? The voice sounded more natural but worse or ordinary when batteries were starting to get weak.)


Anyway, coming back to the topic. The reverb delay was heard in an extended low speed way on where the lyrics say "you know it's truuuueeeeeeeee".


Is the reverb effect sent to the tape recorder to be delayed rather than the dry signal tape delayed and set to the reverb?


If this is the case that should be the trick used at Columbia CBS 30th street New York converted church. If memory is correct engineer Frank Laico would send the reverb from the store-room reverb chamber to tape and get it back delayed.


Abbey road studios had to send visiting engineers to see how they got that sound.
