The JCM800 series (Models 2203, 2204, 2205, and 2210) is a line of guitar amplifiers made by Marshall Amplification.The series was introduced in 1981. Although models 1959 and 1987 had been in production since 1965 and the 2203 and 2204 had been in production since 1975, they were redesigned and introduced as JCM800 amplifiers in 1981.
Bi-amping is the use of two channels of amplification to power each loudspeaker within an audio system. Tri-amping is the practice of connecting three channels of amplification to a loudspeaker unit: one to power the bass driver , one to power the mid-range and the third to power the treble driver .
Mesa-Boogie Mark IV, a guitar combo 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.
Soon after the Rose-Morris deal had ended in late 1980, Marshall repackaged two MV models, the 2203 and the 2204 (at 100 and 50 watts, respectively), along with the 1959 and 1987 non-master volume Super Lead in a new box with a new panel, and called it the "JCM800" series (named after his initials and the registration plate of his car).

In some cases, tube and solid-state technologies are used together in amplifiers. A common setup is the use of a tube preamplifier with a solid-state power amplifier. There are also an increasing range of products that use digital signal processing and digital modeling technology to simulate many different combinations of amp and cabinets.
A simple and robust solution is to use paralleled voltage followers, which by design have exactly unity gain, driven by a common voltage amplification stage. In addition, small resistors (much less than the load impedance, not shown in the schematic) are added in series with each amplifier's output to enable proper current sharing between the ...
AMP launched in September 2020 at $0.009 and was in a generally pessimistic trend up until February 2021. After falling to $0.003, AMP had its first rally in February 2021.
The Marshall Bluesbreaker is the popular name given to the Models 1961 and 1962 guitar amplifiers made by Marshall from 1964/65 to 1972.. The Bluesbreaker, which derives its nickname from being used by Eric Clapton with John Mayall & The Bluesbreakers, is credited with delivering "the sound that launched British blues-rock in the mid-1960s."
