The EarthQuaker Devices Transmisser Resonant Reverberator isn't so much a reverb pedal as it is an entire soundscape galaxy in a box. It features a three-knob reverb control section with parameters for decay (tail length), freq (low pass filter frequency), and darkness (reverberated overtones) along with a three-knob modulation section with controls for rate (modulation speed), warp (modulation depth and length), and mix. Filling the room with enormous, lush digital reverb that's as tweakable as the universe is big, this pedal's added expression jack will have any player spending hours exploring deep space.
