Mesa Boogie Mark Series
The Mesa Boogie Mark Series is a series of guitar amplifier made by Mesa Engineering (more commonly known as "Mesa/Boogie"). Originally just referred to as "Boogies," the product line took on the moniker "Mark Series" as newer revisions were put into production. The Mark Series amplifier was Mesa's flagship product until the introduction of the Rectifier series, and the amplifiers are collectable. Mark I Randall Smith began Mesa/Boogie with a practical joke: he borrowed a Fender Princeton (a small 12-watt amplifier) from his friend, Barry Melton of Country Joe and the Fish, and "hotrodded" it by replacing the amplifier section with a powerful Fender Bassman amp and installing a 12-inch speaker instead of the original 10-inch. The resulting amplifier proved to be loud and successful, and Smith made more than 200 of these Princeton "Boogies"—a name allegedly provided by Carlos Santana, who is to have exclaimed "Man, that little thing really boogies!"

MIDI
MIDI (; Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper ''Universal Synthesizer Interface'' published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and loudness. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, which t ...

John Petrucci
John Peter Petrucci (born July 12, 1967) is an American guitarist, best known as a founding member of the progressive metal band Dream Theater. He produced or co-produced (often with former member Mike Portnoy before he departed the band in 2010) all of Dream Theater's albums from '' Metropolis Pt. 2: Scenes from a Memory'' (1999) to ''A View from the Top of the World'' (2021), and has been the sole producer of the band's albums released since ''A Dramatic Turn of Events'' (2011). Petrucci has also released two solo albums: ''Suspended Animation'' (2005) and ''Terminal Velocity'' (2020). Early life and influences John Peter Petrucci was born on July 12, 1967, in Kings Park, New York, to an Italian American family. He picked up the guitar at around the age of eight because his older sister was allowed to go to bed later in order to practice the organ. However, he decided to quit the guitar when his attempts to stay up late were unsuccessful. He picked up the guitar again at the ag ...

Dream Theater
Dream Theater is an American progressive metal band formed in 1985 under the name Majesty by John Petrucci, John Myung and Mike Portnoy while they attended Berklee College of Music in Boston, Massachusetts. They subsequently dropped out of their studies to concentrate further on the band that would eventually become Dream Theater. Their current lineup consists of Petrucci, Myung, vocalist James LaBrie, keyboardist Jordan Rudess and drummer Mike Mangini. Over the course of various lineup changes, Petrucci and Myung have been the only two constant members, and Portnoy remained with the band until 2010, when he left to pursue other musical endeavors and he has since been replaced by Mangini. After a brief stint with Chris Collins (singer), Chris Collins, followed by Charlie Dominici (who was dismissed from Dream Theater not long after the release of their When Dream and Day Unite, first album), LaBrie was hired as the band's singer in 1991. Dream Theater's first keyboardist, Kevin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tone Stack
A tone stack is a specialized type of audio filter incorporated into the circuit of an audio amplifier for altering the frequency response of the amplifier. The term is primarily used in reference to instrument amplifiers such as guitar amplifiers. The simplest tone stacks are derived from a bridged T network implemented with resistors in place of inductors, creating a notch filter. These will utilize 3 capacitors and 3 resistors in the form of potentiometers. The Fender Bassman 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 pe ... was the first amplifier to standardize the tone stack design. Dubbed the 5F6-A, this tone stack offered the performer the ability to control the amplifier's low, mid, and high frequency response independently. References * {{Electronics-stub ...

Triode
A triode is an electronic amplifying vacuum tube (or ''valve'' in British English) consisting of three electrodes inside an evacuated glass envelope: a heated filament or cathode, a grid, and a plate (anode). Developed from Lee De Forest's 1906 Audion, a partial vacuum tube that added a grid electrode to the thermionic diode (Fleming valve), the triode was the first practical electronic amplifier and the ancestor of other types of vacuum tubes such as the tetrode and pentode. Its invention founded the electronics age, making possible amplified radio technology and long-distance telephony. Triodes were widely used in consumer electronics devices such as radios and televisions until the 1970s, when transistors replaced them. Today, their main remaining use is in high-power RF amplifiers in radio transmitters and industrial RF heating devices. In recent years there has been a resurgence in demand for low power triodes due to renewed interest in tube-type audio systems by audiophi ...

Pentode
A pentode is an electronic device having five electrodes. The term most commonly applies to a three-grid amplifying vacuum tube or thermionic valve that was invented by Gilles Holst and Bernhard D.H. Tellegen in 1926. The pentode (called a ''triple-grid amplifier'' in some literature) was developed from the ''screen-grid tube'' or ''shield-grid tube'' (a type of tetrode tube) by the addition of a grid between the screen grid and the plate. The screen-grid tube was limited in performance as an amplifier due to secondary emission of electrons from the plate. The additional grid is called the ''suppressor grid''. The suppressor grid is usually operated at or near the potential of the cathode and prevents secondary emission electrons from the plate from reaching the screen grid. The addition of the suppressor grid permits much greater output signal amplitude to be obtained from the plate of the pentode in amplifier operation than from the plate of the screen-grid tube at the same plate ...

Class AB Amplifier
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier's characteristics and performance. The classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a signal waveform applied to the input. A class A amplifier is conducting through all the period of the signal; Class B only for one-half the input period, class C for much less than half the input period. A Class D amplifier operates its output device in a switching manner; the fraction of the time that the device is conducting is adjusted so a pulse-width modulation output is obtained from the stage. Additional letter classes are defined for special-purpose amplifiers, with additional active elements or particular power supply improvements; sometimes a new letter symbol is used by a manufacturer to promote its proprietary design. Power amplifier classes Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fetron
The Fetron was a range of solid-state, plug-compatible replacements for vacuum tubes (valves). Fetrons were manufactured by Teledyne Semiconductor from 1967; primarily as a low-maintenance and low-power swap-in to replace vacuum tubes, which were becoming increasingly obsolete and difficult to source with the widespread use of solid-state electronics. They were used in large numbers in telephone exchanges. Vacuum tubes use significant amounts of power to maintain operating temperature, and large installations had substantial air-conditioning requirements; replacing them with fetrons was expected to reduce cooling and maintenance costs. A typical fetron consisted of a cascode configured pair of JFETs, some simple RC networks to control the device characteristics, and a fuse. The device was mounted in a metal tube with a base that has the same pin-out as the vacuum tube that it replaced. Use Fetrons were used to upgrade oscilloscopes and similar test equipment. They were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphic Equalizer
Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric equalizers have much more flexibility in tailoring the frequency content of an audio signal. Broadcast and recording studios use sophisticated equalizers capable of much more detailed adjustments, such as eliminating unwanted sounds or making certain instruments or voices more prominent. Since equalizers "adjust the amplitude of audio signals at particular frequencies" they are, "in other words, frequency-specific volume knobs." Equalizers are used in recording studios, radio studios and production control rooms, and live sound reinforcement and in instrument amplifiers, such as guitar amplifiers, to correct or adjust the response of micro ...

Reverb
Reverberation (also known as reverb), in acoustics, is a persistence of sound, after a sound is produced. Reverberation is created when a sound or signal is reflected causing numerous reflections to 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 of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
