I bought this as a cheap reverb pedal until I could afford an electro harmonix holy grail

This is about 1/3 the cost of the Holy Grail, and the foot switch should hold up well under normal stage use (unless of course, you are an elephant).

It even has a "modulated" reverb, which is a reverb with a slight flange/chorus affecting the reverb signal only (not the dry signal) which is their version of the Holy Grail's "Flerb" setting.

On the other hand, the reverb from my Korg AX-100G (that I was using on another rig) was great.
