Fat Dog, the founder and owner of Berkeley's Subway Guitars, died Oct. 30 at 80, Berkeleyside reported.

He was also known as Fatdog, Fatdawg or Fatty, and rarely used his birth name, Samuel Cohen. Subway Guitars has served as a musical shop and gathering place in Berkeley for generations. Berkeleyside described him as a tinkerer who built guitars out of discarded parts and crafted unusual instruments, and as a figure of the city's counterculture who turned that work into a long-running shop.
