From the Chairman

I would like to personally thank you for selecting one of my vintage re-issue amplifiers.

The Marshall reputation has been built upon many things, but our longevity comes mainly as a result of the continual relevance of the concepts behind the design and build of our amplifiers. Added to this are solid workmanship, reliability, stylish looks, and above all – great tone. The continual fascination and love that many guitarists show for our vintage amplification is a testament to just how relevant and important these models still are today.

The amp you have just acquired was originally launched in the 1960s. A time when the face and sound of popular music was rapidly changing and players were constantly pushing back the musical boundaries. Each of these amps was there at the beginning of this music revolution and all played their part. From Pete Townshend, Eric Clapton and Jimi Hendrix, to Jeff Beck and Paul Kossoff, the list of great ‘tone’ players who pioneered the use of the natural distortion from these amps, reads like a who’s who of guitar players.

Our re-issues of these models are as faithful as possible to the originals in terms of looks and tone. Hand-crafted in the UK these superb units feature finger-jointed cabinets of birch plywood, hand-welded chassis’s, hand-wired potentiometers and valve bases and the highest quality PCBs and componentry.

I would like to wish you every success with your new amplifier and welcome you to the family of great players who use the classic Marshall tone.

Marshall Amplification, a legendary name in the world of electric guitar amplifiers, has played a pivotal role in the music industry since its inception in 1962. The company’s steadfast dedication to craftsmanship and innovation is exemplified in its iconic amp models, such as the JTM45, 1959SLP, and 1987X. These amplifiers have become staples for musicians seeking powerful sound and tone.

The Marshall JTM45, introduced in the early 1960s, was one of the brand's first commercially successful amplifiers. It featured a 45-watt design, driven by two EL34 power tubes, which contributed to its rich and warm tone. The JTM45 utilized a simple layout of just two channels: Normal and Bright, allowing guitarists to achieve a breadth of tonal variety. This model was heavily inspired by the Fender Bassman circuit but refined with Marshall’s distinct twists, giving it a unique British voice. Its durability and versatility made it the choice of many rock legends.

Another notable model is the 1959SLP, referred to as the "Plexi." This 100-watt amplifier gained immense popularity during the late 1960s and early 1970s. Characterized by its four EL34 power tubes and seven preamp tubes, the 1959SLP is famed for its ability to produce a harmonically rich overdrive, perfect for rock and blues music. The amp's straightforward control layout lets players dial in precise tones with ease, encompassing a wide range of sonic possibilities. It has been used by countless famous guitarists, solidifying its status as a rock icon.

The 1987X, a quintessential representative of the Marshall sound, is a 50-watt tube amp that caters to modern musicians wanting classic vibes. This model is designed to replicate the vintage aesthetic and tonal characteristics of its predecessors while incorporating improvements in reliability and practicality. Featuring two channels and a simple control set, the 1987X delivers a powerful crunch that many desire for genres spanning from classic rock to heavy metal.

Marshall Amplification distinguishes itself not only through its iconic amps but also through its commitment to sound quality and performance. The use of premium materials, meticulous hand-wiring in certain models, and a focus on authenticity allow the company to deliver products that resonate with musicians around the world. Ultimately, Marshall’s legacy continues to influence the sound of rock music, forging an unbreakable bond between amplifier technology and the evolving landscape of guitar-driven music.
