There’s no arguing that the Marshall Silver Jubilee is one of the best hard rock amps of all time. Famed players such as John Frusciante, Slash, and Rich Robinson have all utilized the Silver Jubilee in their music – so of course buzz came around when Marshall has reissued the amp in all of its glory. Two channels that go from chiming cleans to hot-rodded distortion, the Jubilee can do it all. The 2555X circuitry is taken from original 2555 diagrams and had been checked against the 2555 head in the Marshall museum. With modern production techniques Marshall was also able to make some improvements to the electronics; switching circuitry has been improved to avoid a relay flickering problem found on some original 2555s. Improved (DC) heaters ensure no noise, and there are external bias points on the amp for ease of repair and retubing. Black fiberglass wires that are high temperature and high voltage resistant were used, and the multi-pin connectors have been improved with higher insertion force and current capabilities but remain PVC, just like the originals.
