What Changed in 1966

Guild moves from Hoboken, NJ to Westerly, RI — a pivotal transition year. Some 1966 D-40s were built at Hoboken, some at Westerly. The transition instruments are especially interesting to collectors.

Collector's Notes

Factory of origin is critical for 1966. Internal markings or features may help identify Hoboken vs Westerly production. Hoboken-built 1966 examples are the last of the original factory era.

How to Authenticate a 1966 Guild D-40

Guild maintained excellent serial number records — verify the number on the neck block or interior label against Guild tables for 1966. Hoboken, NJ production — considered the most collectible era. Mahogany back and sides with spruce top. Mahogany-body dreadnought (Guild's equivalent to Martin D-18). Simpler appointments than D-55. Distinctive Guild arched-back construction. Check Guild headstock logo and chesterfield inlay — style changed over decades. Verify bridge is original, check for top cracks, neck angle, and structural integrity. Tuners should be Grover Rotomatic. Finish should be nitrocellulose lacquer with natural wear. Original case adds value.
