and 1971 tours and some early shows of the 1972 tour, and the bass version by Bill Wyman on the 1972 tour and some of the 1973 Winter tour shows. In 1971, citing lack of compensation for his contributions to the V-series amplifiers, Armstrong left Ampeg, and refused to renew the agreement allowing manufacture his guitar and bass. Changes in ownership (1971―1985) In 1971, Ampeg was acquired by Magnavox, which owned musical instrument manufacturer Selmer, but was better known for televisions, radios and hi-fi components. The following year, Magnavox dissolved Ampeg’s incorporation and moved Ampeg’s management to the Selmer-Magnavox offices in Elkhart, Indiana. In 1974, amidst economic struggles and production capacity surpluses, Magnavox closed Ampeg’s Linden plant, moving production to a portion of a Magnavox electronics factory there. In 1978, SVT designer Bill Hughes left the company. In 1980, Ampeg was acquired by Music Technology, Inc. (MTI), a wholesaler specializing in amplifiers from Japan and keyboards from Italy looking to expand. Under MTI management, SVT and V series amps were prototyped for production in Japan (though V series were never produced). MTI also introduced five new solid-state amps and six new tube amps for Ampeg, and a series of effects pedals. But after production issues and substandard sales, MTI declared bankruptcy a few years later. St. Louis Music and LOUD (1986―2018) In 1986, St. Louis Music (SLM) acquired the assets of Ampeg, including the rights to the name and all remaining MTI inventory. SLM converted leftover V5 heads into SVT-100s and set out to re-create the SVT, setting aside a room at SLM Electronics for an intensive development project. Working from original SVT drawings and parts purchase orders from 1969, the team created a run of 500 amplifiers in 1987 dubbed the Limited Edition SVT-HD amps. SLM then re-established Ampeg manufacturing in its Borman Avenue factory in St. Louis, introducing fourteen new Ampeg guitar and bass amps and the world’s largest bass amplifier at the 1987 summer NAMM Show. In 2005, LOUD Technologies Inc. purchased St. Louis Music and its brands, including Ampeg and Crate amplifiers, ending their production at the Yellville, Arkansas facility in March 2007, outsourcing amplifier manufacture to contract manufacturers in Asia. In May 2018, following the purchase of Loud Technologies Inc. by Transom, the Ampeg brand was acquired from the restructured LOUD Audio LLC by Yamaha Guitar Group, Inc.
