The Gibson ES series, named after ES (Electric Spanish) were initially produced in the Kalamazoo plant in Michigan USA. Two models were initially produced, large semi hollow bodied arch top shaped guitars with f-shaped sound holes in the body, 3×2 tuning pegs and stoptail bar or trapezoid tail pieces. Additionally there was a choice of inlays, one with rosewood fretboard and dot inlays.
Originally with dot markers only, from 1964 these were issued with block shaped fret board position markers in use. This ES Model type guitar played a prominent role in the evolution of rock & roll, blues and jazz.
