This page gives details of two similar guitar amplifiers, the Gretsch 6161 Dual-Twin and 6162 Dual-Twin Reverb. As the name suggests, both were two-speaker (two Jensen ten inch) 17 watt tube amps with built in Tremolo. Again, as the name suggests, the only difference between these models was the Reverb available to the 6162. Priced at $175 and $249.50 respectively (1965 US prices).
