Before there was these $900 enormous reverb pedals we see everywhere, there was a simple little box that added some space to your place; the Holy Grail. It's still a simple, effective little reverb that'll add a little sauce nicely. This is the newer small footprint version with a regular 9v input; nice and convenient.
