A great description from an ebay listing:
“The Silvertone 1464 is a solid state piggyback amp introduced in 1966. What do I mean by piggyback? You have your beautiful and solid cab loaded with Jensen Special Design 12” speakers and a little space at the bottom for your amp head to slide in underneath. The head has two channels with two inputs per channel. Reverb and tremolo are on channel two. One very cool feature is the VERY long cord which connects the head to the cab. Probably a good seven feet long and great for isolated recording. Visit this website for everything Silvertone.”
