Plays great!\u003c\/p\u003e\n\u003cp\u003eThe\u003cstrong\u003e 1972 Marshall JMP Model 1987\u003c\/strong\u003e is one of the defining British valve amplifiers of the classic rock era. Rated at 50 watts and powered by a pair of EL34 output valves, this non-master volume head delivers the unmistakable Marshall roar that shaped countless recordings throughout the 1970s. Positioned between the earlier Plexi models and the later master volume JMPs, the 1972 version combines vintage warmth with a tighter, more aggressive character that has made it one of the most sought-after vintage amplifiers on the market. The Model 1987 retained the classic two-channel, four-input layout with independent Bright and Normal channels, giving players plenty of flexibility, especially when jumpering the channels together. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuild Quality\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLike most early 1970s Marshalls, the 1972 JMP was built to last. The steel chassis, hand-wired turret board construction, and robust transformers contribute not only to its legendary reliability but also to its unmistakable tone. Original examples are highly prized.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSound\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe first thing you'll notice is the immediacy of the amp. It has incredible touch sensitivity, responding effortlessly to your picking dynamics and guitar volume control. Clean tones are bright, punchy and full of harmonic detail, but there isn't a huge amount of clean headroom. Turn the volume past halfway and the amp begins to produce the glorious overdrive that has become synonymous with classic rock.\u003c\/p\u003e\n\u003cp\u003eThe Bright channel provides crisp attack and plenty of bite, making it perfect for cutting through a band mix. The Normal channel offers a fuller, warmer response with more low-end weight. Jumpering both channels together unlocks an even richer sound, allowing you to blend brightness with warmth to create one of the most iconic guitar tones ever recorded.\u003c\/p\u003e\n\u003cp\u003eUnlike later Marshall models with master volume controls, the 1972 1987 needs to be turned up loud before it reaches its sweet spot. When it does, it produces thick, harmonically rich overdrive with excellent note separation and an organic compression that modern amplifiers often struggle to replicate.\u003c\/p\u003e\n\u003cp\u003eAlthough rated at 50 watts, the Model 1987 is astonishingly loud. Through a quality 4x12 cabinet loaded with Celestion Greenbacks, it easily delivers enough volume for virtually any stage.\u003c\/p\u003e\n\u003cp\u003eThe amp excels with classic rock, blues rock, hard rock and early heavy metal. Players chasing the sounds of Angus Young, Paul Kossoff, Michael Schenker or early AC\/DC will immediately appreciate its raw authority and expressive feel. Many guitarists also favour the 50-watt 1987 over the larger 100-watt Model 1959 because it reaches natural power valve saturation at slightly more manageable volume levels\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLegendary classic Marshall tone\u003c\/li\u003e\n\u003cli\u003eOutstanding touch sensitivity\u003c\/li\u003e\n\u003cli\u003eRich, dynamic valve overdrive\u003c\/li\u003e\n\u003cli\u003eSuperb build quality\u003c\/li\u003e\n\u003cli\u003eExcellent platform for vintage and modern pedals\u003c\/li\u003e\n\u003cli\u003eHighly collectable vintage amplifier\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe \u003cstrong\u003e1972 Marshall JMP Model 1987\u003c\/strong\u003e remains one of the finest rock amplifiers ever built.
