The Holy Trinity in the area is fuzz, echo, and univibe; individually and any combination of the three. Eventide already nailed the first two in other algos. If they can nail the univibe sound then the combination will be an epic trippy-hippy algo. Even tide can do it. It’s just a matter of time.
Robert Keeley has the Dark Side (digital) pedal directed to exactly this and it sounds great. So far, though, the pedal only has the processing power to offer two of the three at any given time. It does show that digital can produce an excellent univibe.
