About this listing
Marshall JMP 1959 Super Lead 100 – 1978A superb 1978 Marshall JMP 1959 Super Lead 100, representing one of the most iconic and enduring amplifier circuits Marshall ever produced.By the late 1970s, the 1959 Super Lead had evolved from its Plexi-era origins into the familiar metal-panel JMP format, but the fundamental recipe remained wonderfully simple: 100 watts, four inputs, two channels and no master volume. The result is the huge, immediate and incredibly dynamic Marshall sound that has underpinned generations of rock guitar.This example is presented in very good condition for its age, retaining plenty of its original character and showing the kind of honest wear you'd expect from an amplifier approaching 50 years old.The amplifier retains its original output transformer, while the mains transformer has previously been replaced with a quality Modulus replacement. We always prefer to be completely transparent about changes to vintage equipment, and this is reflected in both the description and pricing of the amplifier.Tonally, it's everything you'd want from a good 100-watt Super Lead: enormous headroom, a firm and authoritative bottom end, aggressive upper mids and an exceptionally immediate response to the guitar. Turn it up and the clean punch progressively gives way to the rich, harmonically complex crunch that made the Super Lead one of the definitive sounds of rock guitar.The two channels can also be jumpered, allowing the brighter Lead channel to be blended with the warmer Normal channel for a surprisingly broad range of sounds.Fully ServicedThe amplifier has recently undergone a professional service by Prestige Amp Servicing and is fully tested and ready to use.The service included:Two OEM Marshall ECC83 valves fitted to V2 and V3Two incorrect 470pF capacitors replacedMains socket replacedDedicated chassis earth fittedSelectors stripped, cleaned and re-tensionedAll six valve sockets attended toFull inspection and testingSpecificationModel: Marshall JMP 1959 Super LeadYear: 1978Serial Number: 01095KPower: 100 wattsConfiguration: Non-Master Volume Lead headInputs: Four-input / two-channelPower section: 4× EL34Mains Transformer: Modulus replacementOutput Transformer: OriginalCondition: Very good for its ageProfessionally serviced: July 2026Original Cover IncludedService documentation includedThe 1959 Super Lead needs little introduction. It's one of the amplifiers that established the Marshall sound and remains one of the benchmarks for big, uncompromising British valve tone.This is a particularly usable vintage example: it retains its original output transformer and has been thoroughly serviced, while the replacement Modulus mains transformer means it can be enjoyed as intended without pretending to be a completely untouched collector's piece.Worldwide shipping available. The amplifier will be carefully prepared and securely packed using purpose-made packaging, with fully tracked and insured delivery.
