This is a Hamer USA T51 90's Green Telecaster Guitar w/Piezzo & Case. Guitar is in excellent shape. Collector kept with minimal signs of play. I'm sure may of you Hamer guys know more about this guitar as far as specs go...all I know is that this is one of the best Tele's that you will ever play!! From what I know the Piezzo version of this guitar is pretty rare so don't let it get away!
