>The Dunlop Univibe sparked off not just some of the best rock music, but one of the coolest-sounding arms races in the world of effects technology. Blue Cat’s PolyVibe takes the recipe for the Univibe, as well as some ingredients from later tributes to the original sound, and puts them all into a single plugin. With exact control over the filter shapes and LFO properties, as well as the ability to choose between three algorithms determining the process behind the actual effect, PolyVibe lets you dial in a wide variety of classic rotary, Univibe, chorus and flanger effects. A free demo is available, so you can easily check out whether it gives you the right vibes before buying.
