The Marshall 1959 Modified 100W guitar amp head is a tribute to one of the most iconic amplifiers in music history. This amp, rooted in the legacy of the original Marshall 1959 "Plexi" and countless rock legends, delivers the same raw, unmistakable sound that defined a generation of guitarists. With its modern enhancements and versatile features, the 1959 Modified is ready to inspire a new generation of players.

The Sound That Shaped Rock and Roll

The Marshall 1959, affectionately known as the "Plexi," gained its legendary status throughout the '60s and '70s, defining the tone of classic rock and blues with its rich, dynamic sound. From Jimi Hendrix to Jimmy Page to Angus Young, countless guitar heroes have relied on the 1959's harmonically rich overdrive and natural dynamics to craft their signature sounds. The 1959 Modified captures the essence of this iconic tone, delivering the same powerful roar that has fueled countless classic recordings.

Modern Enhancements for Enhanced Versatility

The 1959 Modified brings the classic "Plexi" sound into the modern age with several key modifications. The addition of a master volume control allows you to achieve the amp's legendary high-gain crunch at any volume level, making it ideal for home, studio or stage use. The switchable bright cap provides further tonal flexibility, allowing you to dial in either vintage brightness for cutting through the mix or a warmer, smoother tone. The gain boost switch offers two distinct modes of overdrive, expanding your sonic palette with both classic breakup and a higher-gain, more aggressive tone.

Faithful Recreation With Modern Flexibility

The 1959 Modified is a faithful recreation of the original 1959, capturing the essence of its iconic tone while offering modern upgrades that enhance its versatility and control. With its signature 100-watt Super Lead power and iconic plexiglass panel, the "Plexi sound" is faithfully reproduced, delivering the same raw power and dynamic response that defined a generation of rock music. The added master volume, switchable bright cap, and gain boost switch provide modern players with the tools they need to shape their sound and explore new sonic territories.

A Legacy of Craftsmanship and Innovation

The Marshall 1959 Modified is a testament to Marshall's longstanding commitment to craftsmanship and innovation. This amp is crafted with precision at their Bletchley, England factory, ensuring that every detail meets the highest standards. The 1959 Modified is more than just a reissue; it's a tribute to Marshall's heritage, built for today's players who demand the best in tone, versatility and performance.
