Fender Amplifiers have a long history. Leo Fender began building guitar amps before he started manufacturing guitars. The first of these amps were the K&F models, which were produced between 1945 and 1946. The original Fender amps were tube-powered and the company also started producing solid-state models in the late 1960s.
