An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
An audio power amplifier amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones. Audio power amplifiers are found in all manner of sound systems including sound reinforcement, public address, home audio systems and musical instrument amplifiers like guitar amplifiers. It is the final electronic stage in a typical audio playback chain before the signal is sent to the loudspeakers.
Vox is a British musical equipment manufacturer founded in 1957 by Thomas Walter Jennings in Dartford, Kent, England. The company is most famous for making the Vox AC30 guitar amplifier, used by The Beatles, The Rolling Stones, The Kinks, The Yardbirds, Queen, Dire Straits, U2, and Radiohead; the Vox Continental electric organ, the Vox wah-wah pedal used by Jimi Hendrix, and a series of innovative electric guitars and bass guitars. Since 1992, Vox has been owned by the Japanese electronics firm Korg.
An instrument amplifier is an electronic device that converts the often barely audible or purely electronic signal of a musical instrument into a larger electronic signal to feed to a loudspeaker. An instrument amplifier is used with musical instruments such as an electric guitar, an electric bass, electric organ, electric piano, synthesizers and drum machine to convert the signal from the pickup or other sound source into an electronic signal that has enough power, due to being routed through a power amplifier, capable of driving one or more loudspeaker that can be heard by the performers and audience.
A guitar amplifier is an electronic device or system that strengthens the electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 6-inch speaker and a 10-watt amp to heavy combo amps with four 10-inch or four 12-inch speakers and a 100-watt amplifier, which are loud enough to use in a nightclub or bar performance.
Marshall Amplification designs and manufactures music amplifiers and speaker cabinets. Founded in London by Jim Marshall, shop owner and drummer, the company is based in Bletchley, Milton Keynes, England. Marshall Amplification is one of several divisions of Stockholm-based Marshall Group since March 2023.
A valve audio amplifier (UK) or vacuum tube audio amplifier (US) is a valve amplifier used for sound reinforcement, sound recording and reproduction.
The Vox AC30 is a guitar amplifier manufactured by Vox. It was introduced in 1958 to meet the growing demand for louder amplifiers. Characterised by its "jangly" high-end sound it has become widely recognized by British musicians and others, such as George Harrison and John Lennon of the Beatles, Bill Wyman of the Rolling Stones, Brian May of Queen, Dave Davies of the Kinks and Hank Marvin.
A bass amplifier is a musical instrument electronic device that uses electrical power to make lower-pitched instruments such as the bass guitar or double bass loud enough to be heard by the performers and audience. Bass amps typically consist of a preamplifier, tone controls, a power amplifier and one or more loudspeakers ("drivers") in a cabinet.
Distortion and overdrive are forms of audio signal processing used to alter the sound of amplified electric musical instruments, usually by increasing their gain, producing a "fuzzy", "growling", or "gritty" tone. Distortion is most commonly used with the electric guitar, but may also be used with other electric instruments such as electric bass, electric piano, synthesizer and Hammond organ. Guitarists playing electric blues originally obtained an overdriven sound by turning up their vacuum tube-powered guitar amplifiers to high volumes, which caused the signal to distort. While overdriven tube amps are still used to obtain overdrive, especially in genres like blues and rockabilly, a number of other ways to produce distortion have been developed since the 1960s, such as distortion effect pedals. The growling tone of a distorted electric guitar is a key part of many genres, including blues and many rock music genres, notably hard rock, punk rock, hardcore punk, acid rock, and heavy metal music, while the use of distorted bass has been essential in a genre of hip hop music and alternative hip hop known as "SoundCloud rap".
The Univox Hi-Flier is an electric guitar marketed and sold by Univox from roughly 1967 to 1980. With its reversed offset body, the Hi-Flier has an intentional resemblance to the Mosrite Ventures model. A bass version of the Hi-Flier was also available.
Matsumoku Industrial was a Japanese manufacturing company based in Matsumoto, Nagano, between 1951 and 1987. Established in 1951 as a woodworking and cabinetry firm, Matsumoku is remembered as a manufacturer of guitars and bass guitars, including some Epiphone and Aria guitars.
Luxman is a brand name of Japanese Luxman Corporation (ラックスマン株式会社) that manufactures luxury audio components. Luxman produces a variety of high-end audio products, including turntables, amplifiers, receivers, tape decks, CD players and speakers.
Kalamazoo is the name for two different lines of instruments produced by Gibson. In both cases Kalamazoo was a budget brand. The first consisted of such instruments as archtop, flat top and lap steel guitars, banjos, and mandolins made between 1933 and 1942, and the second, from 1965 to 1970, had solid-body electric and bass guitars.
The Fender Super was a guitar amplifier made by Fender between 1947 and 1963 and, as the Super Reverb, until 1981. Though it was designed for a clean sound, its overdriven sound is praised by players and critics.
Lyle guitars were made in Japan between 1960 and the late 1970s in the Matsumoku guitar factory, which also produced Univox, Arai, Aria and other guitar brands. Some Lyle guitars were made in Korea, including the C-600 classical model.
TYM Guitars is a manufacturer of custom guitars and bass guitar based in Brisbane, Australia, as well as custom instruments the company also repairs, restores, refinishes vintage instruments. The line of custom guitars and basses built by TYM Guitars are influenced by manufacturers such as Mosrite, Rickenbacker, Epiphone, Danelectro, Fender and other models from the 1950s and 1960s, with several replicas and hybrids between different models being built to fit customer demand. TYM Guitars also has a retail shop that sells new and secondhand instruments and accessories from their own line of products and other manufacturers.
The Vox Custom 24 was one of a group of guitars produced in Japan by the Matsumoku company between 1980 and 1985, which included the Custom and Standard 24 and Custom and Standard 25 guitars. Custom and Standard bass guitars were also included in the range. Matsumoku had already produced guitars for Aria and other brands such as Westbury. These were recognised as leaders in performance, innovation and quality. The electronics in these guitars were designed by Adrian Legg. The guitars are passive but the complex switching allows for a wide variety of sounds, making them extremely versatile instruments.
A keyboard amplifier is a powered electronic amplifier and loudspeaker in a wooden speaker cabinet used for the amplification of electronic keyboard instruments. Keyboard amplifiers are distinct from other types of amplification systems such as guitar amplifiers due to the particular challenges associated with making keyboards sound louder on stage; namely, to provide solid low-frequency sound reproduction for the deep basslines that keyboards can play and crisp high-frequency sound for the high-register notes. Another difference between keyboard amplifiers and guitar/bass amplifiers is that keyboard amps are usually designed with a relatively flat frequency response and low distortion. In contrast, many guitar and bass amp designers purposely make their amplifiers modify the frequency response, typically to "roll-off" very high frequencies, and most rock and blues guitar amps, and since the 1980s and 1990s, even many bass amps are designed to add distortion or overdrive to the instrument tone.
Vintage musical equipment is older music gear, including instruments, amplifiers and speakers, sound recording equipment and effects pedals, sought after, maintained and used by record producers, audio engineers and musicians who are interested in historical music genres. While any piece of equipment of sufficient age can be considered vintage, in the 2010s the term is typically applied to instruments and gear from the 1970s and earlier. Guitars, amps, pedals, electric keyboards, sound recording equipment from the 1950s to 1970s are particularly sought. Musical equipment from the 1940s and prior eras is often expensive, and sought out mainly by museums or collectors.
