The EarthQuaker Devices Transmisser is a fairly unusual, now-discontinued modulated resonant reverb. EQD describes it as an extra-long-decay reverb feeding a highly resonant filter—much more of a psychedelic/ambient sound-design pedal than a conventional reverb. It is no longer in production, which gives it some collectible appeal.
