This is one of the first Rickenbacker amplifier models to feature built-in tremolo, indicated in this and other Rick amp examples by the “A” designation following the model number. Features an early uncoded Jensen 12” speaker (possibly not the original speaker) and a thick plastic strap handle with aluminum end-caps. These handles – used through the early ‘60s – were made of a thick plastic substance not reinforced with metal; many decomposed or broke; the one on this amp has stood the test of time.
