Legend has it that the first Danelectro UB-2 "Six String Bass" was specially commissioned by Harold Bradley who, as VP of the American Federation of Musicians and president of the Local 257, was trying to get more work for bass players. The "tic tac" bass style, which doubles the acoustic bass, can be heard on 1950s country pop artists, such as Patsy Cline. Since everything was recorded live in stereo back then, this meant two bass players per session instead of one.

The UB-2 was manufactured from 1956 to 1958, and was available in bronze and in black. It followed Danelectro's vision of cheap, efficiently-made guitars that were sold at Sears and other supermarkets under the name Silvertone or Danelectro.

The bodies of the UB-2 are identical to Danelectro's U2 guitars, with a longer neck. They are made of masonite and pine and have two lipstick pickups.

After Danelectro went out of business in the late 1960s, Jerry Jones started making replicas, since the demand from working musicians in Nashville was still quite present. He made these throughout the 1990s until he was shut down by the Evets Corporation, who produces the modern Korean-made reissues.

The Danelectro baritone guitar has been an integral part of Trocadero's sound, usually in a rhythm or support capacity, and occasionally as a lead instrument. The one that is used on our records is a late 1956 model.
