The Marshall JMP01 Preamp was designed by a team of guitarists who think exactly as you do. This great sounding, 1 rack space, easy to use and program, 4-channel preamp offers instant recall of your 100 favorite settings.
The JMP-1's tube driven heart (2xECC83) drives pure tone into each of its four uniquely voiced channels - Clean 1, Clean 2, OD1 and OD2:
Clean 1 is perfect for warm full-bodied chords, fat clean lead passages and jazz tones.
Clean 2 has the glassy edge of a JTM45 for those bright, jangly tones.
OD1 - this channel's smouldering power will take you from the molten gold of a Super Lead Plexi, to searing metal and all points in-between.
OD2 - tightly focused, high gain is served up here by the truckload. Modern and aggressive, yet fluid and toneful. This channel has all the distortion and sustain you'll ever need.

Marshall Rack Gear
Marshall and MIDI To the many rack-addicted axemen out there, it's a marriage made in heaven! By successfully wedding the world famous Marshall tube tone with guitarist friendly MIDI technology, the JMP-1 has firmly established itself as the benchmark in professional, rack preamps. This said, the preamp is only half the story, equally as important in the tone creation chain is, of course, the power amplifier. As we all know, nothing beats the musical roar of a British valve power amp - and nothing roars with more toneful power than a Marshall.
Marshall's expertise in making full use of the 3-D tonality offered by tubes has led to their tube-driven power amps becoming revered by musicians the world over. As a result, the models in Marshall's tube power amp line will breathe new life into the sound of your rack.
