The Vibro-Champ is a classic low wattage design, that's equally suited for practice, recording, and gigging. The Silverface era is a great value alternative to the Blackface models, and the Champ circuits stayed pretty much identical through the 70's, unlike the larger amps. This amp is in great condition, with only minor signs of previous wear. The front grillcloth has been changed, and it also has a replacement backpanel. The speaker is an unlabeled alnico (probably 70's) but it sounds great! Internally, the power cord and electrolytic caps have been changed, but it is otherwise all stock.
