Marshall JMP-1 Tube MIDI Guitar Preamp

Sound Quality

Wow! This baby EATS ADA for breakfast. It's perhaps not as comprehensive as the TRI-AXIS but for what it costs it's power to weight ratio is far more impressive. It's like compairing pontiac to a Dodge Viper! It's very noiseless for something with such high gain, but Marshall have all those years of experience up there sleeve..


Never had a problem. Very sturdy construction. Once again, experience counts.

General Comments

I would and have recomended this unit to many people, and as a result Marshall have sold about 5 more of these. The only thing I wish it could do (which would simply be a ROM upgrade) is support MIDI Continuous Controllers for Volume, Gain, and maybe the tone controls.
