Fender Reverb Unit
The Fender Reverb Unit (6G15) was a vacuum tube, spring reverb-equipped effects unit made by Fender. The Reverb Unit was originally introduced in 1961. It was discontinued in 1966 and was replaced by a solid-state model, the FR1000. The unit features three controls: Dwell, Mixer and Tone and includes a 12AT7 tube as a preamplifier; a 6K6 tube as the reverb driver; and a 12AX7 as the reverb recovery tube. The rectifier is a diode-type solid state unit. The circuit board, like Fender's Brownface, Blackface and Silverface amplifiers is an eyelet board and the unit its completely hand wired. The spring reverb “tank” is mounted on the interior side of the front baffle in a vertical position. Tanks were supplied by Gibbs and Accutronics in the original version. The vertically mounted tank should be a 4AB3C1C (last letter in Accutronics model designation indicates tank orientation) but most actually shipped with 4AB3C1B tanks which are designed for horizontal mounting; these are ...

Vacuum Tube
A vacuum tube, electron tube, thermionic 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. It takes the form of an evacuated tubular envelope of glass or sometimes metal containing electrodes connected to external connection pins. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental Electronics, electronic functions such as signal amplifier, amplification and current Rectifier, rectification. Non-thermionic types such as vacuum phototubes achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light and measurement of its intensity. In both types the electrons are accelerated from the cathode to the anode by the electric field in the tube. The first, and simplest, vacuum tube, the diode or Flem ...

Reverb
In acoustics, reverberation (commonly shortened to reverb) is a persistence of sound after it is produced. It is often created when a sound is reflected on surfaces, causing multiple reflections that build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, their amplitude decreasing, until zero is reached. Reverberation is frequency dependent: the length of the decay, or reverberation time, receives special consideration in the architectural design of spaces which need to have specific reverberation times to achieve optimum performance for their intended activity. In comparison to a distinct echo, that is detectable at a minimum of 50 to 100 ms after the previous sound, reverberation is the occurrence of reflections that arrive in a sequence of less than approximately 50 ms. As time passes, the amplitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Effects Unit
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. Common effects include distortion (music), distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamics (music), dynamic effects such as volume pedals and Dynamic range compression, compressors, which affect loudness; linear filter, filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as Chorus (audio effect), chorus, flangers and phaser (effect), phasers; Pitch (music), pitch effects such as pitch shifter (audio processor), pitch shifters; and time effects, such as Reverb effect, reverb and Delay (audio effect), delay, which create echoing sounds and emulate the sound of different spaces. Most modern effects use solid-state electronics or digital signal processors. Some effects, particularly older ones such a ...

Fender Musical Instrument Corporation
The Fender Musical Instruments Corporation (FMIC, or simply Fender) is an American manufacturer and marketer of musical 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. The company was founded in Fullerton, California, by Clarence Leonidas "Leo" Fender in 1946. Andy Mooney has served as the chief executive officer (CEO) since June 2015. In January 2020, Servco Pacific became the majority owner after acquiring the shares of TPG Growth. History Origins The company began as "Fender's Radio Service" in late 1938, in Fullerton, California. As a qualified electronics technician, Fender had repaired radios, phonographs, home audio amplifiers, public address systems and musical instrument amplifiers, all designs based on research developed and relea ...

12AT7
12AT7 (also known in Europe by the Mullard–Philips tube designation of ECC81) is a miniature nine-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. In television applications, beside the tuner section, it was used just like 12AU7, in vertical and horizontal time base, as line and frame oscillator, relay tube, separator, limiter and also as keyed and gated automatic gain contr ...

Preamplifier
A preamplifier, also known as a preamp, is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a loudspeaker. Without this, the final signal would be noisy or distorted. They are typically used to amplify signals from analog sensors such as microphones and pickups. Because of this, the preamplifier is often placed close to the sensor to reduce the effects of noise and interference. Description An ideal preamp will be linear (have a constant gain through its operating range) and have high input impedance (requiring only a minimal amount of current to sense the input signal) and low output impedance (when current is drawn from the output there is minimal change in the output voltage). It is used to boost the signal strength to drive the cable to the main instrument without significantly degrading the signal-to-noise ratio (SNR) ...

12AX7
12AX7 (also known as ECC83) is a miniature dual-triode vacuum tube with high voltage gain (electronics), 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 (typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Fender Amplifier
Fender amplifiers are electric instrument amplifiers produced by the Fender Musical Instruments Corporation. The first guitar amplifiers attributed to Leo Fender were manufactured by the K&F Manufacturing Corporation (K&F) in 1945. Later, Fender began building its own line of electric guitars. Fender amplifiers would become favorites of guitarists like Jimi Hendrix, Eric Clapton, and Stevie Ray Vaughan, also known in these cases for playing Fender guitars. Fender amps have come in many configurations and styles. The early K&F and Fender amplifiers relied upon vacuum tube circuitry, with solid-state models appearing in the late 1960s. Fender frequently updated the internal circuitry of its amps, and changed their appearance throughout its history. Early amplifiers: K&F, Woodie and Tweed The first "Fender" amplifiers were manufactured by Leo Fender and Doc Kauffman, doing business as the K&F Manufacturing Corporation.
