Danelectro Commando
The Danelectro Commando is a combo guitar amplifier manufactured by Danelectro from 1954 to 1960. There is some evidence that it may be one of the many different amplifiers used by Little Walter. The circuitry of this 30-watt amplifier is typical of its day, with a 5Y3 rectifier tube, one 12AX7 preamp tube, one 12AX7 for phase inversion, a 6SN7 additional gain stage, four 6V6 The 6V6 is a beam-power tetrode vacuum tube. The first of this family of tubes to be introduced was the 6V6G by Ken-Rad Tube & Lamp Corporation in late 1936, with the availability by December of both Ken-Rad and Raytheon 6V6G tubes announced. ... power tubes, and a 6SJ7 (1954-1958) or a 6AU6 (1958-1960) for the built-in vibrato unit. What makes it unique is the cabinet. Employing a "suitcase" design, it contains eight 8-inch Rola 10610 alnicos speakers wired series / parallel in two arrays one in either side of the suitcase, with the amplifier and controls located at the top and bottom of one side. ...

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] |
Danelectro
Danelectro is a brand of musical instruments and accessories, founded in Red Bank, New Jersey in 1947. The company is known primarily for its string instruments that employed unique designs and manufacturing processes. The Danelectro company was sold to the "Music Corporation of America" (MCA) in 1966, moving to a much larger plant in Neptune City, New Jersey, employing more than 500 people. Nevertheless, three years later Danelectro closed its plant. In the late 1990s, the Evets Corporation started selling instruments and accessories under the Danelectro name. In 2016, Danelectro introduced new models, including a resonator guitar. Some of the products manufactured by Danelectro include electric and resonator guitars, basses, electric sitars, amplifiers, pickups, and effects units. History Danelectro was founded by Nathan "Nat" Daniel in 1947. Throughout the late 1940s, the company produced amplifiers for Sears, Roebuck and Company and Montgomery Ward, branded Silvertone and ...

Little Walter
Marion Walter Jacobs (May 1, 1930 – February 15, 1968), known as Little Walter, was an American blues musician, singer, and songwriter, whose revolutionary approach to the harmonica had a strong impact on succeeding generations, earning him comparisons to such seminal artists as Django Reinhardt, Charlie Parker and Jimi Hendrix.Glover, Tony; Dirks, Scott; and Gaines, Ward (2002). ''Blues with a Feeling: The Little Walter Story''. Routledge Press. His virtuosity and musical innovations fundamentally altered many listeners' expectations of what was possible on blues harmonica.Dahl, BilLittle Walter: Biography Allmusic.com. He was inducted into The Rock and Roll Hall of Fame in 2008, the first and, to date, only artist to be inducted specifically as a harmonica player. Biography Early years Jacobs' date of birth is usually given as May 1, 1930, in Marksville, Louisiana. He was born without a birth certificate and when he applied for a Social Security card in 1940, his birthdate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
6SN7
6SN7 is a dual triode vacuum tube with an eight-pin octal base. It provides a medium gain (20 dB). The 6SN7 is basically two 6J5 triodes in one envelope. History Originally released in 1939 it was officially registered in 1941 by RCA and Sylvania as the glass-cased 6SN7GT, originally listed on page 235 of RCA's 1940 RC-14 Receiving Tube Manual, in the Recently Added section, as: 6SN7-GT. Although the 6S-series tubes are often metal-cased, there was never a ''metal-envelope'' 6SN7 (there being no pin available to connect the metal shield); there were, however, a few glass-envelope tubes with a metal band, such as the 6SN7A developed during World War II - slightly improved in some respects but the metal band was prone to splitting. Numerous variations on the 6SN7 type have been offered over the years, including: * 7N7 (Sylvania 1940, short-lived loktal-base version), * 1633 (RCA 1941, also for 26-V radios), * 12SX7 (RCA 1946, intended for use in 12-volt aircraft electronics), * ...

6AU6
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 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 amplification and current 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—from the cathode to the anode. Ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instrument Amplifiers
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, synthesizers and drum machine to convert the signal from the pickup (with guitars and other string instruments and some keyboards) or other sound source (e.g, a synthesizer's signal) 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. Combination ("combo") amplifiers include a preamplifier, a power amplifier, tone controls, and one or more speakers in a cabinet, a housing or box usually made of hardwood, plywood or particleboard (or, less commonly, moulded plastic). Instrument amplifiers for some instruments are also available withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
