The Marshall JCM-1H Head is part of Marshall’s 50th Anniversary celebration. This killer amp is part of a limited edition series of 1W tube head and combo pairings – each pair paying homage to one of the five decades that Marshall has been in business. Two 12AX7 pre-amp tubes and a single ECC82 power tube give an authentic JCM800 tone. The era correct cosmetics, including white Marshall script logo plus JCM800 detail and styling will give an authentic 80s style. The Boost Switch adds more gain and provides tone character from another definitive ‘80s Marshall; the Marshall 2555..
