With 16Hz-20kHz of bandwidth inside one stereo programmable box, the Alesis QuadraVerb Plus upgrades the original QuadraVerb with a bevy of new features. With the new QuadraVerb Plus, you have easy-programming access to multi-tap delay, sampling, auto panning, trem, ring mod, and even five distinct resonators for pitch generation. Use one of these effects or many in tandem or stacked - whatever you choose, the QuadraVerb Plus' touch-sensitive programming buttons make it easy to plug in effects or recall one of the 100 storable programs.
