4 channel overdriving I am still 2 b convinced of anything better than a Spirit ... my 2 cents.

PS- the Digital yamaha's have the pre-amps. b4 the conversion 2 digital so u do get a decent overdrive... but they're not as phat as Mackie or Spirit ... on resonable amouts adds more punch that really distortion ... if u go will it will squash yet sound 2 a pulp... still very good for industrial ou extreme hardcorish stuff!
