: Serial numbers were often just production sequence numbers rather than date-encoded strings.
For certain 2021 models (like the NXT A100), guitars produced in that year typically have a 43mm nut and 650mm scale , whereas 2022 models transitioned to a 46mm nut. Identifying Vintage Eko Guitars
For a guitar manufactured in , the serial number follows a specific logic.
Let’s walk through two real-world examples of an performed in 2021.
| Serial Number Range (approx) | Year Estimate | Origin / Notes | | :--- | :--- | :--- | | 1000 – 4900 | 1962 – 1964 | Early Italian production. Very rare. | | 5000 – 9900 | 1965 – 1966 | Peak “Beatlemania” era. | | 10000 – 29999 | 1967 – 1969 | Transition from round to pointed headstocks. | | 30000 – 59999 | 1970 – 1973 | Often “A” prefix or no prefix. | | 60000 – 89999 | 1974 – 1978 | Quality declining. Spanish production begins. | | 90000 – 150000 | 1979 – 1985 | Mostly Spanish-built. Generic designs. |
