The Cathedral Stereo Reverb Pedal from Electro-Harmonix is a digital reverb pedal with seven different types of programmable reverb plus digital echo, all of which work in true stereo. The pedal can save and load up to eight presets, one preset for each different mode. There is a Damping/Tone control available for each reverb mode, which allows further refinement of the sound. The Tap Tempo footswitch sets the pre-delay for up to two seconds, with Feedback allowing for reverberant echoes. The unit runs on the included US96DC-200BI power supply.
