An audio power amplifier is an electronic amplifier that 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.
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, 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 is a British company that designs and manufactures music amplifiers, speaker cabinets, brands personal headphones and earphones, drums and bongos. The company also owns a record label called Marshall Records. It was founded in London by drum shop owner and drummer, Jim Marshall, and is now based in Bletchley, Milton Keynes, England.
Dumble was a guitar amplifier manufacturer in Los Angeles, California.
The Ibanez Tube Screamer (TS808/TS9) is a guitar overdrive pedal, made by Ibanez. The pedal has a characteristic mid-boosted tone popular with blues, rock and metal players. The Tube Screamer has been used by many guitarists to create their signature sound, and is one of the most successful, widely copied, and custom-modified ("modded") overdrive pedals in the history of the electric guitar.
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 KT88 is a beam tetrode/kinkless tetrode vacuum tube for audio amplification.
A treble booster is an effects unit used by guitarists to increase the high end of their tonal spectrum. Many units boost the overall volume as well. Treble boosters were commonly used by guitarists in the 1960s and 1970s. During the last couple of decades, their popularity has increased again and many clones and reissues of the classic circuits have become available.
The Marshall Bluesbreaker is the popular name given to the Models 1961 and 1962 guitar amplifiers made by Marshall from 1964/65 to 1972.
The Marshall Super Lead Model 1959 is a guitar amplifier head made by Marshall. One of the famous Marshall Plexis, it was introduced in 1965 and with its associated 4×12″ cabinets gave rise to the "Marshall stack".
This is a list and description of the guitars and other equipment played by musician Stevie Ray Vaughan. Vaughan played a number of Fender Stratocasters throughout his career, one of which, a 1963 body and a late 1962 rosewood neck, became "the most famous battered Strat in rock history." He was notoriously hard on his guitars, and many of them required extensive periodic maintenance, as well as other equipment. He used a limited number of effect pedals, and favored Fender and Marshall amplification.
The Fender Deluxe guitar amplifier is a range of non-reverb guitar amplifiers produced by Fender. The amplifiers were originally produced from early 1948 to 1966 and reissues are in current production. Its predecessor was the Fender Model 26 "Woodie" produced from 1946 to 1948.
Blackstar Amplification is a British company that produces and manufacturers guitar amplifiers and effects units. The company was founded by a group of ex-Marshall employees, most notably Bruce Keir, who became technical Director at Blackstar, and former Chief Design Engineer at Marshall, Ian Robinson. In 2009 the company began operations in the United States. The majority of the research and development for Blackstar is carried out in the UK. Blackstar is endorsed by major artists like Ozzy Osbourne, Kurt Viehdorfer, Neal Schon, Opeth, Richie Sambora of Bon Jovi. Blackstar has been consistently ranked amongst the best amplification brands by leading guitarists. Bruce Keir died in September 2021 at the age of 60.
The Marshall JTM45 is the first guitar amplifier made by Marshall. First produced in 1963, it has been called a "seminal" amplifier, and is praised as being among the most desirable of all the company's amplifiers.
The JCM800 series is a line of guitar amplifiers made by Marshall Amplification. The series was introduced in 1981. Although models 1959 and 1987 had been in production since 1965 and the 2203 and 2204 had been in production since 1975, they were redesigned and introduced as JCM800 amplifiers in '81. The JCM800 amplifiers became a staple of 1980s hard rock and heavy metal bands.
Traynor is a brand of bass amplifiers and guitar amplifiers, the first brand formed by Yorkville Sound. The Traynor brand, named for founder Peter Traynor, began in 1963 with the Dynabass bass amplifier, a rental product. Traynor first became popular in Canada by providing less expensive versions of the circuits used in Marshall and Fender amplifiers of the time. The revived brand now produces a wide range of electric, acoustic, and bass guitar amps.
Fuzz bass is a style of playing the electric bass or modifying its signal that produces a buzzy, distorted, overdriven sound, as the name implies. Overdriving a bass signal significantly changes the timbre, adds higher overtones (harmonics), increases the sustain, and, if the gain is turned up high enough, creates a "breaking up" sound characterized by a growling, buzzy tone.
