The Dean ML is an electric guitar made by Dean Guitars in 1977 along with its counterparts, the Dean V, Dean Cadillac and Dean Z. It has an unusual design, with a V-shaped headstock and V-shaped tailpiece. It was popularized by the guitarist Dimebag Darrell of Pantera.
Dean Zelinsky created the ML in 1977, striving for improved sustain and tone. Higher string angles and string length, due to the size of the headstock, contribute to the overall resonance.
The ML was named posthumously for the initials of Zelinsky's friend Matthew Lynn, who had died of cancer.
