It has been 30 years since Sears ended its association with the Silvertone brand, but the public's association is so strong to this day that many still believe Silvertone is a Sears brand. It is a testament to the success and quality of Sears' Silvertone products that the public still associates the two names so closely. The Sears Silvertone radio and Silvertone guitar, two highly collectible items today, are largely responsible for America's fond recollection of the Sears-Silvertone connection. In 1915, Sears introduced the Silvertone phonograph, a hand-cranked machine that came in tabletop and freestanding models. All phonographs came with a two-week, money-back guarantee. HISTORY: Sears began selling Silvertone radios in the early 1920s, soon adding Silvertone radio tubes and batteries to the product line. In the late 1930s, however, Silvertone radios quickly took off in popularity. The era corresponded with the outbreak of military aggressions in the Pacific theater. With the approach of World War II, increasing numbers of people wanted radios not just for entertainment, but also to receive updates on the war's progress, according to contemporary company sales analyses. During World War II, Sears introduced the Silvertone radio antenna with "stratobeam reception." And to help power the radios, Sears sold Silvertone wind generators. The Silvertone name replaced the Supertone brand on musical instruments in the 1930s. Struggling blues musicians of the 1940s and 1950s first popularized the Silvertone guitar, with legends such as Muddy Waters and Arthur "Big Boy" Crudup among those who played Silvertone. The Sears Silvertone guitar really made its mark in music history as the unofficial "first guitar" of guitar's icons. Chet Atkins, Bob Dylan and Jimi Hendrix, among many others, played their first chords on a Sears Silvertone. Sears' guitars have even been immortalized by their mention in songs from artists as diverse as Mary Chapin Carpenter ("Girls With Guitars") and G. Love and Special Sauce ("Blues Music"). Silvertones were popular with young musicians because of their solid construction and inexpensive pricing. Their legacy lives on today as literally hundreds of Internet pages are filled with fond recollections from people of their first guitar, the Sears Silvertone. As with the Silvertone radio, Sears Silvertone guitars are considered prized pieces of many guitar collections, particularly models such as the 1963 "amp-in-case" guitar, which featured an amplifier built into the guitar's carrying case. Many other musical and audio items bore the Silvertone brand name. Sears introduced a Silvertone record label in the 1920s, featuring many of the era's most popular recording artists. In the 1950s and early 1960s, the Silvertone brand name appeared on all Sears electronic equipment, including console televisions, tape recorders, walkie-talkies, radio batteries, hearing aids and car radios.
