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.
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.
Electro-Harmonix is a New York City-based company that makes electronic audio processors and sells rebranded vacuum tubes. The company was founded by Mike Matthews in 1968. It is best known for a series of guitar effects pedals introduced in the 1970s and 1990s. EHX also made a line of guitars in the 1970s.
Dumble was a guitar amplifier manufacturer in Los Angeles, California.
The Ibanez Tube Screamer 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.
Musitronics, often shortened to Mu-tron, was a manufacturer of electronic musical effects active in the 1970s. Founded by Mike Beigel and Aaron Newman, the company's products provided filtering and processing effects and were derived from synthesizer components. The company was known for producing high-quality products with many user-adjustable parameters, but high production costs and a failed product line, the Gizmotron, caused its downfall.
The Deacy Amp is an electric guitar amplifier created in 1972 by Queen's bassist John Deacon, who is an electronics engineer by training. The amplifier circuit board from a Supersonic PR80 portable radio found in a builder's skip (dumpster) was fitted into a speaker cabinet and powered by a 9-volt battery. The amplifier had no volume or tone controls and for most of its history it was never broken and thus never repaired. It was used along with Queen lead guitarist Brian May's Red Special electric guitar and treble-booster to produce sounds reminiscent of various orchestral instruments, such as violin, cello, trombone, clarinet, or even vocals, starting from the songs "Mad The Swine" and "Procession" from the 1974 album Queen II.
The Fender Twin and Twin Reverb are guitar amplifiers made by Fender Musical Instruments Corporation. The Twin was introduced in 1952, two years before Fender began selling Stratocaster electric guitars. The amps are known for their characteristically clean tone.
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.
Jennings Musical Instruments is a manufacturer of musical instruments, and the original owner of the Vox brand. The company was founded by Thomas Walter Jennings.
The Fender Hot Rod Deluxe is a guitar amplifier manufactured and sold by the Fender Musical Instruments Corporation. It was introduced in 1996 as part of the "Hot Rod" line of guitar amplifiers and has been in continuous production since. The Hot Rod Deluxe is a modified version of the Fender Blues Deluxe from the earlier Blues line of amplifiers, and has a higher level of gain in its preamplification signal. This model, along with the Hot Rod Deville, were originally designated as F.A.T. amplifiers but this moniker was dropped in 2002 when production of this series of amps was moved from Corona, CA to Fender's Baja-Ensenada, Mexico manufacturing facility.
The Fender Champ was a guitar amplifier made by Fender. It was introduced in 1948 and discontinued in 1982. An updated version was introduced in 2006 as part of the "Vintage Modified" line.
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 Mesa/Boogie Mark Series is a series of guitar amplifier made by Mesa Engineering. Originally just referred to as "Boogies", the product line took on the moniker "Mark Series" as newer revisions were put into production. The Mark Series amplifier was Mesa's flagship product until the introduction of the Rectifier series, and the amplifiers are collectable.
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.
Guitar wiring refers to the electrical components, and interconnections thereof, inside an electric guitar. It most commonly consists of pickups, potentiometers to adjust volume and tone, a switch to select between different pickups, and the output socket. There may be additional controls for specific functions; the most common of these are described below.
The Fender Vibroverb was a 40-watt combo guitar amplifier originally manufactured in 1963 and 1964. It was the first Fender amplifier to incorporate on-board reverb and tremolo/vibrato, which became a standard feature on many high-end Fender tube amps during the 1960s and 1970s.
Jim Kelley Amplifiers is the trademark for the vacuum tube guitar amplifiers designed by Jim Kelley and manufactured by his company Active Guitar Electronics of Tustin, California between the years of 1978 and 1985. Approximately 600 of these amps were built during that time. The single-channel version of the amplifier employed modest gain in the preamp stages, Baxandall type bass and treble controls, a split load phase inverter, and four 6V6GT output tubes. The amplifiers produce 60 watts RMS at full power, and include a half power (30/60) switch.
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.
