From the Eastman website:
"The 52nd Street Saxophone is a professional instrument and comes un-lacquered for a truly vintage appearance. It is an exceptionally responsive horn in all registers from low to high, and produces a big, fat sound with precise intonation. A larger bell and rolled-style tone holes contribute to the sound qualities of this instrument that many compare to some of the great vintage horns of the past. Solid construction with comfortable hand position and extras such as adjustable palm keys."
