The iconic Marshall Silver Jubilee was produced for a single year—1987. They now fetch ridiculous sums of money on auction sites when they come up for sale—which isn’t often. Several years after that first release, Marshall put out the Slash signature amp based on the same circuitry. That amp, too, became an object of lust. Needless to say, a legend (and a speculative collectors’ niche) grew—along with a market eager to see a reissue. Marshall has heeded the clamor with the new JCM 25/50 2555X Silver Jubilee.
