1958 Gibson Les Paul

Gibson serial numbers from this era are ink-stamped on the back of the headstock. Cross-reference with known Gibson serial tables — numbering was not strictly sequential. Potentiometer date codes are critical: look for CTS pots (code 137) with two-digit year codes matching 1958 or up to 18 months earlier. This is the most reliable dating method for Gibson guitars of this era. The finish should be nitrocellulose lacquer showing age-appropriate checking (fine crazing). Under blacklight, original nitro fluoresces a distinctive green-yellow — refinished instruments lack this characteristic. Verify original PAF (Patent Applied For) humbucker pickups — check for the distinctive sticker on the baseplate. PAF bobbins, wire routing, and Alnico magnets should be consistent with 1958 production. PAFs are the most frequently counterfeited Gibson component — DC resistance should read approximately 7.5-9k ohms. The carved maple top over mahogany body is a key construction detail — check body weight (originals are typically 8-10 lbs). Gold top finish should show natural aging to warm brass-yellow. Examine the neck joint tenon — long tenon is correct for this era. Check for headstock repairs (Gibson headstocks are prone to breaking) — repairs reduce value significantly. Original Kluson Deluxe double-ring should be present with no evidence of replacement (no oversized bushing holes). Original hardshell case adds provenance value.
