The idea of blending amps together has been a studio trick used on countless recordings over the years. Being able to blend the strengths of certain amplifiers and have other amps fill in the weaknesses produces a richer, better balanced sound. Up until now, the only way to repoduce this live was to haul a few amps around with you on the road. After a few gigs of doing that, a lot of players end up compromising tone for the ease of carrying 1 amp around with them. This is where the multidrive shines.
The multidrive allows you to blend Overdrive, Distortion and Fuzz together, creating a full and rich array of tones that would not be available otherwise. Let the sustain of fuzz, the bite of distortion and the clarity and note definition of overdrive all work together! It's like having an overdrive pedal, a fuzz pedal, and a distortion pedal, all in one box.
