DiMarzio HS-3 Guitar Pickup I had this installed at a repair shop a long time ago (over 10 years?) because I was hesitant about the appearance of the Yngwie model Stratocaster, and I recently removed it. There's no manufacturer or part number written anywhere, but is that normal...? I always leave guitar repairs to the shop, so I won't be able to answer any detailed questions. Sorry! There's no case either. - Included: Screw set Thank you for looking.
