John Bogdanovich Guitars 1996 to present “I began building guitars in 1996. The early labels had the date and a serial number. I stopped putting a serial number on the label after a few years but all labels still have the year the guitar was built. At about the same time I also began to burn my signature and the year into the fingerboard patch under the top for authentication which can be seen by inserting a small mirror in through the soundhole.” [Source: John, J.S.
