Collector's Notes
Check for headstock repairs — SG headstock cracks are the most common issue. Original cherry finish should show natural darkening. Verify pickup originality.
How to Authenticate a 1975 Gibson SG
Check the impressed (stamped) serial number on the headstock back — verify within documented 1975 ranges. Potentiometer date codes are critical: look for CTS pots (code 137) with two-digit year codes matching 1975 or up to 18 months earlier. This is the most reliable dating method for Gibson guitars of this era. By the early 1970s, Gibson was transitioning to thicker finishes. Check finish thickness and aging characteristics. Verify original humbuckers — check baseplate markings and construction details consistent with 1975 production. Thin mahogany body, devil-horn cutaway. Check for headstock repairs — SG's thin neck joint is fragile. Cherry red finish should show fading toward orange-pink. Original Grover Rotomatic should be present with no evidence of replacement (no oversized bushing holes). Original hardshell case adds provenance value.
