Released in 1992, the Dual Rectifier Solo Head opened up a new paradigm for high-gain guitars. This amplifier, created by MESA Engineering, produced a groundbreaking sound with a cut midrange, a heavy low end, and a sharp top end rich in harmonics, all woven together like a powerful wall of tube gain. Like its sound, this amp provided a powerful playing experience, supporting the improvement of my technique, inspiring me, making it a rewarding and addictive amplifier to use. The sound and influence this amplifier had on the generation that shaped the future of rock music is immeasurable and continues to this day. It has become one of the most used and imitated tube amplifiers in history, and even in today's world of digital amplifiers, it is probably the most modeled amplifier. With its harmonically rich gain and deep bass, the "Recti" became a major guitar amp, driving powerful crunch rhythms and exciting lead and octave hooks. With its options for freely adjusting sound and feel, it became a go-to choice for musicians seeking maximum breadth and depth in a three-piece band, and its look provided a backdrop for an aggressive style. With respect and pride, we present the 90s Dual Rectifier. This amp faithfully recreates the tube amps that redefined the concept of high gain and graced many soundtracks of a generation, and it features welcome upgrades such as improved clean sound. This is your chance to acquire a truly legendary amplifier, crafted by the same artisans who created the original 30 years ago, in like-new condition with a warranty.
