This 1970s Champ has a simple enough circuit that it remained practically unchanged from the Blackface era. This amp is all original, with the exception of the grillcloth on the front panel, along with the handle and chassis strap hardware. The tolex has a shiny appearance on the top due to being oversprayed with black to cover up a previous paint spill. The sound is excellent on this particular Champ, making it a great value for the money.
