Arion DCF-1 Digital Chorus Flanger Rare Vintage Guitar Effect Pedal MIJ Japan

Purchased by my uncle many years ago when he thought he was going to be a rock star.  Sat in a closet and never used.  Box shows wear but unit has never been used.  The front of the box has writing (Price in black sharpie in 2 locations) on it as my uncle had it in his garage sale.  I told him I would sell it on eBay for him as he would get more for it.
