A tabletop digital reverb unit, the MicroVerb can also accept a footswitch to be used more easily by guitarists. 16 different reverb types include six "Small" settings, seven "Large" settings, two gated reverbs, and one awesome reverse reverb. It does have a strange power plug. It's a nine-volt AC "headphone plug" type, but many will be sold with replacements already. And if not, replacement plugs are easy to find.
