Haz Labs Mu-Tron III+
December, 2006
HAZ Labs’ Mu-Tron III+ is a faithful reproduction of the original ’70s Musitronics Mu-Tron III envelope filter, with upgraded components. That faithfulness carries through some weird stuff: The jacks are reversed from most pedals, which, together with its immodest size, makes the III+ a pedalboard pest.
There’s no effect-on indicator (the light helps set filter peak or indicates low battery), so you’d better remember whether you turned it off between the funk jam and the ballad. Worst of all, there’s an on/off switch right up front that loudly kills your signal—yikes! Oh, but then there’s the tone. Brimming with juicy, analog slurps, swoops, and quacks—à la Bootzilla—the Mu-Tron III+ has all the sonic options: up or down movement, band selection, and low or high filter sweep. If that’s not enough, dip switches in the battery compartment affect specific performance changes. Deliciously sensitive and warm, the III+ is a tub of buttery fun.
