Sadly, Jim Marshall, the Father of Loud, passed away on april 5th 2012. R.I.P. Dr.Tube humbly salutes the Guv’nor.
Jim Marshall started building amps in 1962. He did this together with Ken Bran and aided by the technical engineer Dudley Craven. Their first amps were very heavily “inspired” on the 1959 Fender Tweed 4×10″ Bassman. Little did they know then that they were at the threshold of a rock ‘n roll revolution…
|1962||The very first Marshall amps that saw the light of day were called the JTM45 amps. These amps were more or less a copy of the Fender 1959 Tweed Bassman. These amps were built as heads (or tops) separated from the speaker cabinets. The speaker cabinets were closed 4×12″ Celestion loaded cabinets.|
|1965||The first combos (models 1961 & 1962) appeared halfway this year.
Desperate to build a factory large enough to meet demand, Jim Marshall made a deal with the Rose Morris company. In exchange for the necessary funding (to build this new factory) Rose Morris acquired the exclusive worldwide rights to distribute Marshall amps for the next 15 years. Due to this deal the Marshall amps were very expensive these following 15 years.
In this year the Plexi face plates were introduced.
The first 100W models were introduced this year.
|1966||The JTM45 panels were changed to the JTM50 panels with the switch to the EL34 output tubes. The GZ34 rectifiers were phased out to be replaced by solid state rectifiers.|
|1967||The hand bent aluminium chassis was replaced by the steel machined chassis, making the amps much more robust and road proof.
The Marshall 200s were introduced this year.
The JTM panels were replaced by the JMP panels.
|1968||The Marshall 200 was redesigned and renamed to the Marshall Major.|
|1969||The Plexi panels were replaced by gold brushed aluminium panels.|

|1981||The introduction of the JCM800 amps.|
|1982||The 20th anniversary of Marshall.
The introduction of the JCM800 Split Channel amps: JCM800 2205 & JCM800 2210.

|1988||The first 1959 and 1987 reissue amps.|

Jim Marshall passes away. RIP.
Viewing this brief history of the Marshall amps, several eras can be distinguished:
- The sixties (1962 – 1967) which is “Jurassic” period of Marshall and is the time of the JTMs.
- The seventies (1967 – 1981) was the era of the JMPs.
- The eighties (1981 – 1989) was the era of the JCM800s and the first anniversary amps.
- The nineties (1990 – 1999) was the era of the JCM900s and the reissues.
- Year 2000+ is the realm of the JCM2000s and the JVMs and 40+ years of Marshall Amps.
Although this division is not entirely accurate, it does give a good impression of the different eras. The first decade in the history of Marshall is regarded by some as the “Golden Years”.
In the following overview, I try to place the amps in some kind of chronological ordering. Keep in mind that allthough I try to be complete, this is obviously not a complete list, though I hope it will be some day…
