The 1474 welcomed the 60s with a new sound - reverb - and a new look - the suitcase amp. This look would carry through the early 60s in the 1471/81/72/82. They looked kinda like a TV, kinda like a suitcase, but completely like a Silvertone. One oddity, I've never seen the 'triple 3' controlled model shown in the catalog illustrations, every example I've seen has a '2, 3, 4' knob config.
