From Jim Marshall

ENGLISH

I would like to thank you personally for selecting one of our stereo valve power amplifiers.

Since 1962 the valve has played an incredibly important part in the development of the Marshall Sound and we have been dedicated to the design and manufacture of the world’s finest valve powered amplification.

We are well aware of the special relationship that has formed between the guitarist and the valve over the years, indeed, we have always actively sought to enhance the unique character of our valve amps in order to foster this relationship.

When designing our EL84 20/20, EL34 50/50 and EL34 100/100 Power amps, our valve design experts utilised all the knowledge and skill at their disposal with just one thing in mind - improved performance!

Their combination of traditional Marshall valve technology with new and innovative circuitry, has resulted in designs that are radically different in terms of both looks and performance.

The quality of tone produced by these all valve power amps is truly remarkable and, by reflecting all that is best about Marshall, will become an essential part of any serious stereo rack guitar system.

I strongly suggest that you read this handbook carefully before operating your new stereo valve power amplifier and wish you every success with it.

Sincerely,

EL84 20/20 specifications

Marshall Amplification has built a legacy of producing some of the most sought-after guitar amplifiers in the market, merging classic sound with innovative technology. The Marshall EL84 20/20 stands out as a remarkable offering, aimed at musicians who crave versatility without compromising on tone.

At the heart of the EL84 20/20 are two EL84 power tubes, which deliver 20 watts per channel of rich, dynamic sound. This choice of tubes contributes to a warm and distinctive tonal character, providing that quintessential Marshall crunch favored by many rock and blues guitarists. The amp features two independent channels, allowing players to switch between a clean and overdriven sound effortlessly. Channel one offers a pristine clean tone, while channel two lets players unleash the full fury of Marshall’s legendary overdrive.

One of the notable features of the EL84 20/20 is its innovative power scaling technology. This allows guitarists to control the wattage output, enabling them to achieve optimal sound at any volume level. This feature is particularly beneficial for studio recordings and small venue performances as it allows musicians to push the amp to its sweet spot without overwhelming their surroundings.

Another highlight is the built-in reverb, adding depth and ambiance to the sound. This is particularly useful for live performances, where atmospheric effects can elevate the overall experience. Players can dial in their desired reverb level to complement their tone, making it a valuable addition to the amp's versatility.

The EL84 20/20 is designed with a user-friendly interface, featuring straightforward controls that include gain, treble, middle, bass, and reverb for each channel. This intuitive layout makes it easy for musicians to customize their sound and dial in their ideal tone quickly, whether in the studio or on stage.

In terms of connectivity, this amplifier offers a range of outputs, including speaker outputs that allow for different cabinet configurations, as well as an effects loop for integrating external effects pedals. This flexibility caters to a wide array of performance styles and playing environments.

In summary, the Marshall EL84 20/20 combines classic Marshall tone with modern technology, making it an ideal choice for any guitarist seeking a powerful yet versatile amp. Its signature features, such as the EL84 power tubes, power scaling, reverb, and intuitive controls, ensure that musicians can achieve their desired sound with ease and precision, solidifying its position as a must-have in the world of guitar amplification.
