Hamer Guitars was an American manufacturer of electric
guitars founded in 1973, in
Arlington Heights,
Illinois, by vintage guitar shop owners Paul Hamer,
Jol Dantzig and John Montgomery. The company's early instruments featured guitar designs based on the
Gibson Explorer (The Standard) and
Gibson Flying V (Vector), before adding more traditional
Gibson-inspired designs such as the Sunburst. Hamer Guitars is generally considered the first "boutique" electric guitar brand that specifically catered to professional musicians, and was one of the first guitar manufacturers to produce a
12 string bass guitar.
