10-22-16 Hello, I was at Keith's concert in los angeles on Thursday Oct 20th. I purchased his awesome Ripcord guitar for $499 from inside the event. When I got home and opened the case I expected to find a certificate of authenticity but there was none. I was also wondering if this was a limited edition and if is a numbered guitar (I can't find a number on it). I assumed for the price I paid I would have some paperwork on this item. Please let me know if you can send me any information on this guitar
