N.O.S. (New Old Stock)
As if the guitar was discovered in a warehouse after many years, never played and showing no signs of age or wear.
Closet Classic
A guitar collector's dream! Imagine discovering a vintage guitar at a yard sale that's been stashed in a closet... it's worn a bit, yellowed with age, the finish is slightly checked with hairline finish cracks that are typical of an instrument that's been exposed to years of humidity and temperature variations.
Relic
Super worn-in, like your favourite pair of jeans! Shows natural wear and tear from years of heavy use — nicks, scratches, worn finish, rusty hardware and aged plastic parts. Looks, feels and plays like it's taken the punishment of many long nightclub hours.
Je trouve que ça raconte plutôt bien (même si c'est en anglais) ce que sont les Time Machine
