The Aria Model A555 is a vintage classical nylon-string acoustic guitar manufactured in Japan during the late 1960s and 1970s. Produced during the golden era of Japanese luthiery, these instruments are highly regarded for their robust build quality and rich tonality.
Key Specifications & Tonewoods
  • Top Material: Selected solid reddish Cedar or solid Spruce (depending on the specific year of production).
  • Back & Sides: High-grade bookmatched Rosewood or Sapelli featuring deep, expressive grain patterns.
  • Neck & Fingerboard: Mahogany neck paired with a Rosewood fretboard and a 2-inch nut width.
  • Hardware & Details: Classic wood inlaid mosaic rosette, multi-ply body binding, and standard cream-capped or Waverly tuning machines.
  • Manufacturer: Built primarily out of the legendary Matsumoku factory in Japan, which was renowned for its meticulous wood selection and craftsmanship.
Sound and Playability
The age of the matured woods gives the A555 a remarkably carefree, resonant sound profile. The low-end basses hum warmly, while the trebles are packed with abundant, delicate harmonics. It usually features a comfortable, flat D-shaped neck profile.
Because these guitars are nearly 50 to 60 years old, current market examples range from fair to excellent condition. This guitar is in excellent condition with very little wear.
