Gorilla was a budget amplifier brand in the 1980s onwards. For many guitarists a low powered, solid state, Tawainese made Gorilla was their first amplifier. When Howard Chatt bought the Pignose Amps company in 1985, he re-named it Pignose-Gorilla - possibly Chatt was behind the launch of the Gorilla brand? Circa 2002 the Gorilla line up included:
