I own a few nice acoustic guitars and was in the market to buy another Martin. I was playing one at a Guitar Center and the salesman brought me a PRS Angelus Custom.I had never heard of PRS acoustics line until that moment and I was amazed. I could not forget the sound after a month. I bought it on Friday. The only thing I am missing, which I did not know was important, is a "hang tag". The guitar appears to be made of cocobolo with an adi top and cocobolo fretboard. I would like to know for sure. The serial number on the receipt is a long mix of letters and numbers. Is there a way to find this out and do I need to get the hang tag from Guitar Center?
