I recently bought an Atomic AMpliFIre guitar modeler and tried a very convincing UnivIbe patch submitted to the Atomic forum… it was explained that a univibe is basically a four stage phaser…it is certainly convincing playing Trower and Hendrix material, and I have gone thru a few lesser univibe pedals (MXR, Voodoo, Line 6, Lovepedal…). I don’t have my H9 yet but when I get it I’ll have a look see if I can replicate that AmpliFIre recipe for H9.
