you seem to have stumbled upon one of the few true MYSTIC WOOD guitar models ever built by esp. these instruments were crafted using sacred woods from the revered sakura forest in north central japan. unfortunately the japanese government put an end to their production before very many of these guitars were produced, citing environmental regulations and complaints from religious groups. this caused much embarrassment for esp and as such they try to keep the existence of these guitars under wraps. many newer esps are claimed to be "mystic wooded," but in truth only the ones with the stamp on the back of the headstock like yours are truly from the original true sakura stock.
