This D-tuner has both Hipshot and Schaller imprinted on it and when I bought it used a while back I was told it came of a 70's Precision Bass. Other than that I don't know any model designation. It has the look of a well used piece so it would fit nicely on an older instrument. I'm not entertaining trades and the price, shipped to the 48 states, is 40 including shipping. I take Paypal and will gladly answer all PM's coming my way. Thank you!
