After much customer demand, Marshall is offering the most popular product from its Silver Jubilee range. First released in 1987 to celebrate 25 years of Marshall Amplification, and to commemorate Jim Marshall's 50th year in the music industry, the 2555 has become a legendary and much sought-after amplifier due to its distinct looks, sound and features. The 2555X is a modern-day reissue, featuring all of the original panel features found on the 2555, and reproducing its signature tone perfectly. The Silver Jubilee series was created in 1987 to celebrate the 25th anniversary of the founding of Marshall Amplification and the 50th year of Jim Marshall being in the music business, hence the Silver Jubilee' original 25/50 designation. Based on JCM800 2203 and 2204 Master Volume models, the Jubilee amplifiers were the first Marshall products with Pentode/Triode switching, which halves the power output. Players such as Joe Bonamassa, Slash, Alex Lifeson, and John Frusciante have all included Jubilees in their arsenals and sing the praises of this amp.
