The Relic models are finished in a shabby chic style and aspire to perfectly replicate vintage instruments, both in terms of the parts, design and finishes used, as well in the varying degrees of wear typically found on a 40- to 50-year-old instrument. Fender tarnishes metal parts, purposely marks and scratches paintjobs, yellows and cracks plastic parts, and cigarette burns marks in the headstock (some players allegedly timed jam sessions by cigarette burn time). "Relic-ing" is controversial among players who question the logic of paying a premium for a deliberately damaged instrument. Fender offers grades of wear in the relic series, from light to very heavy 'wear', and has since introduced a line of 'NOS' (new old stock) and 'Closet Classic' instruments that employ period-correct parts, designs and finishes but do not feature faux abuse, weathering, or aging.
