The MPX 1 Multi-Effects Processor fulfills the promise implied by the term "multi-effects." When summoned to do their best reverb, most single DSP multieffect processors run out of gas - you don't get additional effects. The MPX 1 has Lexicon's own proprietary Lexichip, dedicated to delivering uncompromised Lexicon stereo reverb or ambience, in addition to another processor to create the other digital effects. So you get your best reverb, at all times, along with as many as 4 additional stereo effects.
