later found favour with players such as Randy Rhoads, Zakk Wylde and Slash. The 1959 and 1987 non-master volume models also continued under the JMP line until 1982. JCM800 Soon after the Rose-Morris deal had ended in late 1980, Marshall repackaged two MV models, the 2203 and the 2204 (at 100 and 50 watts, respectively), along with the 1959 and 1987 non-master volume Super Lead in a new box with a new panel, and called it the "JCM800" series (named after his initials and the registration plate of his car). Marshall made several amplifiers under the JCM800 name. The Jubilee A landmark year for Jim Marshall was 1987. It marked 25 years in the amplifier business and 50 years in music. This was celebrated with the release of the Silver Jubilee series of amplifiers. The Silver Jubilee series consisted of the 2555 (100 watt head), 2550 (50 watt head) along with other 255x model numbers denominating various combos and even a "short head". The Jubilee amplifiers were heavily based on the JCM800s of the time, featuring a very similar output section along with a new preamplifier. Their most publicised feature was the half-power switching, which is activated by a third rocker switch next to the standard "power" and "standby" switches. On the 50-watt model this was reflected in the numbering – 2550 is switchable from 25 to 50 watts – and also reflected Marshall amplifiers' 25th anniversary and Jim Marshall's 50 years in music. The amplifiers were trimmed in silver covering, and had a bright silver-coloured faceplate, along with a commemorative plaque. The Jubilee also featured a "semi-split channel" design, in which two different input gain levels could be set, running through the same tone stack and master volume control. This allowed for a "classic Marshall" level of gain to be footswitched up to a modern, medium to high gain sound, slightly darker and higher in gain than the brasher JCM800 sound that typified 1980s rock music. "The sound of these amps is particularly thick and dark, even on the Marshall scale of things. The gain by today's standards is medium." The distortion sound of the Jubilee range is typified by Slash's live work with Guns N' Roses. He rarely used anything else live, but oddly the Jubilee did not appear on any Guns N' Roses studio albums – instead these feature a modified 1977 JMP mkII (non-MV) on Appetite
