Why it sounds like that

John Deacon played against the wall with a Marshall bass stack, and his bass was taken direct, with a microphone on the cabinet to pick up a bit of air. He played a Fender Precision Bass: his sunburst P-Bass gave way to a pair of natural-finish Precisions around the A Night at the Opera period, and the isolated bass track has him on a Precision.
