I will 2nd (3rd?) the vote for the Earthquaker Dispatch Master. You can dial the delay function out and use it exclusively as a verb pedal. Very limited adjustability, but one of the cleanest, best sounding verbs I have ever used/heard - period. I have owned and sold numerous reverb units over the years with tweak-ability out the ass that never sounded as good or as clean / transparent as the Dispatch Master. I have a pair of them and use one as verb only and the other as delay only so I can switch the delay on and off independently from the verb. I have never found a reverb stomp that sounded as good as the Dispatch Master.
