From the superb, authentic spring reverb (check out Robben Ford's Spring Fever toneprint) to huge, almost delay-like hall and plate reverbs, there's no reverb sound this pedal can't deliver

In fact, I think the Holy Grail is the best reverb pedal out there if you're looking for the best spring reverb

There is a setting called "Reverb" by a French sound gadget design firm that is a great spring reverb.
