Fender Deluxe Reverb
The Fender Deluxe Reverb is a guitar amplifier made by the Fender Electric Instrument Company and its successors. It was first introduced in 1963 by incorporating an onboard spring reverb tank to the newly redesigned Fender Deluxe amplifier. Specifications The Deluxe Reverb is a 22-watt tube amplifier (at 8 ohms), powered by a pair ("duet") of 7408/6V6GT power tubes, one GZ34/5AR4 rectifier tube, four 7025/ 12AX7 tubes for preamplification and tremolo oscillation, and two 6201/ 12AT7 tubes driving the reverb and phase inverter circuits. Throughout its production, the amplifier has most often featured a Jensen C-12Q series 12-inch loudspeaker, although Oxford 12K5, Marlboro SE, Utah and Eminence speakers have also been used. The 22-watt output was obtained by operating the 6V6 power tubes well in excess of their maximum specified operating voltage. The amplifier weighs 42 pounds and measures 9.5" x 24.5" x 17.5". Variations The original Deluxe Reverb (circuits AA763, and later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guitar Amplifier
A guitar amplifier (or amp) 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 (and preamplifier) 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. Guitar amplifiers can also modify an instrument's tone by emphasizing or de-emphasizing certain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fender Electric Instrument Company
The Fender Musical Instruments Corporation (FMIC, or simply Fender) is an American manufacturer of instruments and amplifiers. Fender produces acoustic guitars, bass amplifiers and public address equipment, however it is best known for its solid-body electric guitars and bass guitars, particularly the Stratocaster, Telecaster, Jaguar, Jazzmaster, Precision Bass, and the Jazz Bass.

Fender Deluxe
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. Tweed Deluxe The Fender Deluxe amp of the 1950s was a medium-powered unit designed to let guitarists "hold their own" in a small group. As blues, western swing, Western, and rockabilly bands began getting louder, the overdriven tone of a cranked-up Deluxe found its way onto many live and recorded performances. The earliest version of the Deluxe was the 5A3, and is often referred to as having a TV Front appearance because the wide panels around the grill were like the television sets of the 1950s. This was true also of the smaller Fender Princeton student and studio amp introduced in 1946 and upgraded in 1948. Subsequent versions of the Deluxe were the "wide panel" cabinet design 5B3, 5C3, and 5D3, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valve Audio Amplifier
A valve audio amplifier ( UK) or vacuum tube audio amplifier ( US) is a valve amplifier used for sound reinforcement, sound recording and reproduction. Until the invention of solid state devices such as the transistor, all electronic amplification was produced by valve (tube) amplifiers. While solid-state devices prevail in most audio amplifiers today, valve audio amplifiers are still used where their audible characteristics are considered pleasing, for example in music performance or music reproduction. Instrument and vocal amplification Valve amplifiers for guitars (and to a lesser degree vocals and other applications) have different purposes from those of hi-fi amplifiers. The purpose is not necessarily to reproduce sound as accurately as possible, but rather to fulfill the musician's concept of what the sound should be. For example, distortion is almost universally considered undesirable in hi-fi amplifiers but may be considered a desirable characteristic in performance. ...

Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rectifier
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The reverse operation (converting DC to AC) is performed by an Power inverter, inverter. The process is known as ''rectification'', since it "straightens" the direction of current. Physically, rectifiers take a number of forms, including Vacuum tube#Diodes, vacuum tube diodes, wet chemical cells, mercury-arc valves, stacks of copper and selenium rectifier, selenium oxide plates, Diode#Semiconductor diodes, semiconductor diodes, silicon-controlled rectifiers and other silicon-based semiconductor switches. Historically, even synchronous electromechanical switches and motor-generator sets have been used. Early radio receivers, called crystal radios, used a "Cat's-whisker detector, cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or "crystal detec ...

12AX7
12AX7 (also known as ECC83) is a miniature dual-triode 6AV6 vacuum tube with high voltage gain. Developed around 1946 by RCA engineers in Camden, New Jersey, under developmental number A-4522, it was released for public sale under the 12AX7 identifier on September 15, 1947. The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications. As a popular choice for guitar tube amplifiers, its ongoing use in such equipment makes it one of the few small-signal vacuum tubes in continuous production since it was introduced. History The 12AX7 is a twin triode basically composed of two of the triodes from a 6AV6, a double diode triode. The 6AV6 is a miniature repackaging (with just a single cathode) of the triode and twin diodes from the octal 6SQ7 (a double-diode triode used in AM radios), which itself is very similar to the older type 75 triode-diode dating from 1930. Application The 12AX7 is a high-gain (typical amplifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
12AT7
12AT7 (also known in Europe by the Mullard–Philips tube designation of ECC81) is a miniature 9-pin medium-gain (60) dual-triode vacuum tube popular in guitar amplifiers. It belongs to a large family of dual triode vacuum tubes which share the same pinout (EIA 9A), including in particular the very commonly used low- mu 12AU7 and high-mu 12AX7. The 12AT7 has somewhat lower voltage gain than the 12AX7, but higher transconductance and plate current, which makes it suitable for high frequency applications. Originally the tube was intended for operation in VHF circuits, such as TV sets and FM tuners, as an oscillator/frequency converter, but it also found wide use in audio as a driver and phase-inverter in vacuum tube push–pull amplifier circuits. This tube is essentially two 6AB4/EC92s in a single envelope. Unlike the situation with the 6C4 and 12AU7, both the 6AB4 and the 12AT7 are described by manufacturer's data sheets as R.F. devices operating up to VHF frequencies.Tu ...

Reverb Effect
A reverb effect, or reverb, is an audio effect applied to a sound signal to simulate reverberation. It may be created through physical means, such as echo chambers, or electronically through audio signal processing. Echo chambers The first reverb effects, introduced in the 1930s, were created by playing recordings through loudspeakers in reverberating spaces and recording the sound. American Producer Bill Putnam is credited for the first artistic use of artificial reverb in music, on the 1947 song "Peg o' My Heart" by the Harmonicats. Putnam placed a microphone and loudspeaker in the studio bathroom to create a natural echo chamber, adding an "eerie dimension". Plate reverb A plate reverb system uses an electromechanical transducer, similar to the driver in a loudspeaker, to create vibrations in a large plate of sheet metal. The plate's motion is picked up by one or more contact microphones whose output is an audio signal which may be added to the original "dry" signal. Plat ...

Jensen Loudspeakers
Jensen Loudspeakers is a company that manufactures speakers in many different models and sizes. Originally located in Chicago, Illinois, the company built a reputation during the 50s and 60s providing speakers used mainly in guitar and bass amplifiers. Although the American company is long out of business, "reissue" guitar speakers are currently made in Italy by SICA Altoparlanti and distributed in the United States by CE Distribution. Jensen and Rola were, for a time both under common ownership (subsidiaries of the Muter Co.), and shared various design similarities. Their 8" and 15" baskets appeared to utilize the same tooling. Rola locations took over Jensen product manufacturing when the Chicago plant closed. The current Fender Twin Reverb amp uses two 12" Jensen C-12K speakers. History The former Jensen Radio Manufacturing Company was founded in 1927 by Peter Laurits Jensen, the co-inventor of the first loudspeaker, in Chicago, Illinois. The company gained popularity in its ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer 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; 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 ...
