The old 8 track players had a way to adjust the head alignment, At least mine did,I always had this thing with 8 tracks of being able to hear a different track than the one selected softly playing under the selected one. I got that ball shaped 8 track player with the AM radio in it for Christmas one year, probably 1975 or 1976. I never really bought a lot of 8 track tapes, though. I was more into albums with their artwork.
