Nope, just plain-jane algorithmic digital reverb. That Eventide box should be perfect for that sort of thing. There's a lot of possibilities in using contact mics, too, especially with something that's designed for that such as the Field Kit. For example, try stretching out a metal Slinky (the plastic ones will not work for this) between two points, and place a contact mix on either end. Then fiddle around with the Slinky...tapping it, springing it back and forth, etc. Or run a signal in one end via a transducer to a contact mic on the other end for utterly fucko bizarro spring reverb craziness. Another fun one: get a ride cymbal and a violin bow. Put the cymbal on a stand and contact mix it right at the top of the bell so the mic doesn't impede its ringing. Now bow the cymbal. MUCH craziness of an ambient-ish variety...sort of like a cheapo version of what Stockhausen was up to with his "Mikrophonie I".
Electronic music doesn't have to involve a synth. Sometimes some weird amplification methods and processing works...sometimes even better!
