This is a Schatten HFN Artist Steel String Guitar Pickup. It's a pickup for acoustic guitars that reproduces a realistic acoustic sound. It was attached to a Yokoyama guitar, but I'm selling it because I replaced it with a Fishman Rare Earth Blend! Retail price: 49,500 yen http://www.tmc-liveline.co.jp/schatten/guitar.html [Brand] Schatten [Model] HFN Artist [Type] Steel String Guitar Pickup Thank you.
