The Uni-Verb is a 5 year project to try and capture the sound of the original. To make it even better we have added a Reverb meant to emulate a classic spring tank reverb from the 50's. It is always best to have the Uni-Verb effect first in the chain and Reverb last in the chain so we have built in a loop to allow you to do so. The originals had a rocker switch to select either vibe or chorus but we have added a foot switch so it can be done on the fly. We paid special attention to making the vibe section very musical and useable compared to the original. The Univerb vibes faster and slower than the original and also has slightly more output.
