Schaller was founded in 1945 by Helmut Schaller (1923–1999), a skilled toolmaker and radio technician. Starting as a radio repair shop, the business expanded in the 1950s to include amplifier and loudspeaker development, eventually leading to the company's restructuring as Schaller Electronic.

By 1953, Schaller began producing guitar components—like pickups and switches—for Framus, one of Germany’s major guitar makers. Other manufacturers such as Höfner, Hopf, and Hoyer soon followed. By the 1960s, Schaller hardware had made its way onto guitars from major American brands like Fender, Gibson, Martin, and Ovation.

In the following years, Schaller broadened its offerings to include tremolos (1961), bridges (1962), and tuning machines (1966). The introduction of the M6 tuner in 1966 marked a major milestone, being the world’s first fully enclosed, self-locking tuner.

In 1968, the company moved to a new facility in Postbauer-Heng. The 1970s saw continued expansion, including M4 bass tuners, TOM bridges for Gibson, and various pickups. Schaller also collaborated with Floyd D. Rose to produce his innovative double-locking tremolo design in 1977.

By the early 1980s, Schaller phased out its audio equipment to focus exclusively on metal hardware for guitars. In 1981, the company patented its now-famous locking strap system, which became one of its most successful and enduring products.
