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.

Laney Amplification is a British designer and manufacturer of guitar amplifiers, bass guitar amplifiers, cabinets, and public address systems, selling them exclusively through a network of distributors and retailers.
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.
A guitar speaker is a loudspeaker – specifically the driver (transducer) part – designed for use in a combination guitar amplifier of an electric guitar, or for use in a guitar speaker cabinet. Typically these drivers produce only the frequency range relevant to electric guitars, which is similar to a regular woofer type driver, which is approximately 75 Hz — 5 kHz, or for electric bass speakers, down to 41 Hz for regular four-string basses or down to about 30 Hz for five-string instruments.
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.
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.
AHED was a Canadian company owned by Phil G. Anderson that produced guitar amplifiers, as well as guitars. Its main product line was the GBX amplifier, which could reach 180 watts with 4x10", 4x12" or 2x15" speakers. The GBX amplifier had a pre-amplifier that could change the gain, brilliance, depth, contour and response of the output.
The Fender Bassman is a series of bass amplifiers introduced by Fender during 1952. Initially intended to amplify bass guitars, musicians used the 5B6 Bassman to amplify other instruments, including electric guitars, harmonicas, and pedal steel guitars. Besides being a popular and important amplifier in its own right, the Bassman also became the foundation on which Marshall and other companies built their high-gain tube amplifiers.
Trace Elliot is a United Kingdom-based bass amplification manufacturer, and has a sub-brand, Trace Acoustic, for acoustic instruments.
Randall Amplifiers is a manufacturer of solid-state and tube guitar amplifiers. Randall Amplifiers is currently a brand of U.S. Music Corp., a subsidiary of Canadian corporate group Exertis | JAM.
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.

Fryette Amplification of North Hollywood, California is a manufacturer of hand-built electric guitar amplifiers, speaker cabinets, power amplifiers, sound effects pedals and pedalboard accessories. The company was founded as VHT Amplification in Studio City, Los Angeles, California by Steven Fryette in January 1989 and was the first to produce a true three-channel vacuum tube amplifier.
HH Electronics is a British amplifier manufacturer that was founded in 1968 by Mike Harrison, Malcolm Green and Graham Lowes in Harston near Cambridge, England, where its first solid state TPA and MA range of studio quality amplifiers were designed and manufactured. These amplifiers were used by many recording and broadcasting studios, including the BBC.
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.
