I recently picked up a Digitech RP 360 to have for practicing and I find that I like it enough to use on gigs. I especially like the spring reverb setting. It sounds pretty realistic to my ear. What Digitech Reverb pedal comes closest to the Spring Reverb setting in the RP? I think that there are three. The Hardwire, The Polera and the Supernatural. And before those were the DigiVerbs.
