A loudspeaker is an electroacoustic transducer, that is, a device that converts an electrical audio signal into a corresponding sound. A speaker system, also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker drivers, an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone, and indeed the dynamic speaker driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such a motor in reverse, as a generator.
Vox is a 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.
A humbucking pickup, humbucker, or double coil, is a type of guitar pickup that uses two wire coils to cancel out the noisy interference picked up by coil pickups. In addition to electric guitar pickups, humbucking coils are sometimes used in dynamic microphones to cancel electromagnetic hum.
JBL is an American company that manufactures audio hardware, including loudspeakers and headphones. JBL serves the consumer home and professional market. The professional market includes studios, installed/tour/portable sound, cars, music production, DJ, cinema markets, etc. JBL is owned by Harman International.
A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly.
Celestion is a British designer and exporter of professional loudspeakers.
Fender amplifiers are a series of electric instrument amplifiers renowned by musicians worldwide. The Fender Musical Instruments Corporation has continuously manufactured guitar amplifiers since their foundation, Leo Fender began building guitar amplifiers even before he started manufacturing electric guitars. The first of these were the K&F models, produced between 1945 and 1946. Fender amplifiers would become favourites of many famous guitarists such as Stevie Ray Vaughan, Jimi Hendrix and Eric Clapton, helping them pioneer their sounds.
The P-90 is a single coil electric guitar pickup produced by Gibson since 1946. Gibson is still producing P-90s, and there are outside companies that manufacture replacement versions. Compared to other single coil designs, such as the ubiquitous Fender single coil, the bobbin for a P-90 is wider but shorter. The Fender style single coil is wound in a taller bobbin but the wires are closer to the individual poles. This makes the P-90 produce a different type of tone, somewhat warmer with less edge and brightness. As with other single-coil pickups, the P-90 is subject to mains hum unless some form of hum cancelling is used.
The Fender Wide Range Humbucker is a humbucker guitar pickup, designed by Seth Lover for Fender in the early 1970s. This pickup was intended to break Fender's image as a "single coil guitar company", and to gain a foothold in the humbucker guitar market dominated by Gibson.
Fender Telecaster Custom is a model of electric guitar made by Fender.
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.
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 Bullet was an electric guitar originally designed by John Page and manufactured and marketed by the Fender Musical Instruments Corporation. It was first introduced as a line of "student" guitars to replace the outgoing Mustang and Musicmaster models.
Electric guitar design is a type of industrial design where the looks and efficiency of the shape as well as the acoustical aspects of the guitar are important factors. In the past many guitars have been designed with various odd shapes as well as very practical and convenient solutions to improve the usability of the object.
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 Bassman is a bass amplifier series introduced by Fender during 1952. Initially intended to amplify bass guitars, the 5B6 Bassman was used by musicians for other instrument amplification, including the electric guitar, harmonica, 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.
The Fender Noiseless series is a line of electric guitar pickups made by the Fender Musical Instruments Corporation. Introduced in 1998, they feature a row of six dual stacked-coil pole pieces, designed to cancel hum noise. This single coil sized stack consists of a row of paired single coils stacked one on top of the other, compacted so as to fit (incognito) into the same size width space as a regular single coil pickup. This is to be contrasted with the original humbucking pickup design, which is a row of paired single coils double wide.
The Fender Telecaster, colloquially known as the Tele, is, an electric guitar produced by Fender. Together with its sister model the Esquire, it is the world's first mass-produced, commercially successful solid-body electric guitar. Its simple yet effective design and revolutionary sound broke ground and set trends in electric guitar manufacturing and popular music.
DUPLEX was the trade name given by Altec Lansing to its line of coaxial loudspeakers, beginning with the first model 601 in 1943. However, the name was most commonly associated with the subsequent model 604 which was a seminal loudspeaker that became a milestone in loudspeaker development. Well over a dozen different models carried the Duplex name over a near 50-year period. The vast majority consisted of a high frequency (HF) compression driver mounted to the back of a large diameter paper cone low frequency (LF) driver. However, there were also a few models with small diameter LF cones and direct radiator tweeters.
