This 1966 Fender Vibro Champ Amp is in Excellent Vintage condition with natural aging of parts and finish plus minor signs of handling and use.  They don't come much cleaner than this.  Sounds just as it should.  

FROM FENDER:

Fender overhauled the Champ in fall 1964 in the “blackface” style—black Tolex covering and black front-mounted control panel with separate bass and treble controls. The tube layout remained the same. 1964 also saw the introduction of model with built-in tremolo called the Vibro Champ. Along with the rest of the Fender amp lineup, the Champ and Vibro Champ adopted the “silverface” style in 1968.
