Introduction

The Marshall re-issue range consists of the 100 Watt 1959SLP head, the 50 Watt 1987X head, the 2245 ‘JTM45’ head and 1962 ‘Bluesbreaker’ combo. All are faithful reproductions of the originals, which shaped the sound of the electric guitar as we know it.

The main characteristic that these amps share is their simplicity of operation and superb natural valve tone. Achieving the beautifully organic and vibrant overdrive which is their trademark, can only be done in one way – crank’em up! The result is pure, majestic tone uncluttered by unnecessary circuitry. With solos this produces a big, round, warm sustain, full of classic character. With chord work you get a bark and percussive attack with a natural sounding break up, which allows each note to ring out in a glorious musical crunch.

FX Loop

Due to high demand, a sonically transparent effects loop has been added to the 1959SLP and 1987X models. This circuitry has been designed to not colour the guitar sound, so that your tone remains pure. The bypass switch gives you the option of completely removing this circuitry if desired. The effects loop level selector ensures compatibility with rack processors or floor pedals (stomp boxes).

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.
