This is the original Holy Grail Reverb from Electro-Harmonix. Still works great. Don't use it anymore so I'm selling it. The pedal is in great condition. There's still velcro tape on the back of it from when it was in my pedal board. And there's also glue residue left over on the plug from when it was glued to the pedal board as well. But everything is in fine working order.
