THD Electronics

Article summary

THD Electronics, Ltd. is a manufacturer of amplifier accessories, and a former manufacturer of vacuum-tube guitar amplifiers. It is located in Seattle, Washington. It was founded in 1986 by President and CEO Andrew Marshall. At one time specializing in hand-built, vacuum tube “boutique”-style amplifiers, it continues to manufacture the “world’s best selling [guitar amplifier] power attenuator,” the THD Hot Plate. The company is well known in the boutique amplifier market, and is often credited with the creation of this market in the United States. THD's line of products stayed relatively small despite its 22-year history as a company. Of its amplifiers, THD made three: the UniValve, BiValve-30, and Flexi-50.
