Endangered Audio Research's AD4096 Analog Delay is one of the most inspiring delay pedals available. It's all analog, with 40–400 milliseconds of warm, yet defined repeats—no MIDI, no tap-tempo, no nonsense. It's one of those pedals that sounds amazing and musical wherever the knobs happen to be set, and plugging into it will cause even the most ardent digital delay fanatic to begin viewing tap-tempo as a needless distraction suitable only for dilettantes and heartless manipulators.
