The classic rotary speaker effect in a box. Three knobs control Rate, Intensity, Volume while two switches switch between Chorus and Vibrato and ON and OFF. This chorus is thick and slushy with a heavy leslie vibe while the vibrato does it's own wonderful wobbly thing. The result makes for some stunning underwater-like textures or pseudo electric piano-like tinklings. The experience gets even trippier and more expressive with the optional foot pedal attached. If you're looking to nail the classic sounds of Hendrix, Pink Floyd, and Zappa, the UniVibe delivers. The unit itself is built like an army tank but looks gorgeous with its soft brushed aluminum surfaces and shiny chrome knobs. This is an reliable effect that can add some special quivering moments to your songs, just be sure to use it with taste and you'll impress and astound.
