What Changed in 1975
Indian rosewood D-45 — the standard post-1970 configuration. The abalone ornamentation remains spectacular. Despite the rosewood change, these are extraordinarily beautiful instruments.
Collector's Notes
The transition from Brazilian to Indian rosewood cuts the value roughly in half. Indian D-45s are still magnificent guitars — the full abalone inlay treatment and spruce top make them exceptional.
How to Authenticate a 1975 C.F. Martin & Co. D-45
Martin serial numbers are the most reliable in the industry — verify the number stamped on the neck block (visible through the soundhole) against Martin's published tables. For 1975, the number should fall within the documented range. Indian rosewood back and sides — verify correct grain and coloring. Non-scalloped X-bracing pattern for this era — verify through the soundhole. The D-45's distinctive abalone pearl bordering on top, back, sides, fingerboard, and headstock must all be original. Verify all inlay and appointments match factory specifications. Check for neck resets, top cracks (especially near soundhole and bridge), and bridge plate condition. Tuners should be Grover Sta-Tite (gold). Finish should be nitrocellulose lacquer with age-appropriate wear. Original case adds value.
