The Warble Swell Echo from Mattoverse Electronics is an analog voiced digital echo/delay with a dynamic foot-controllable Swell feature and gooey modulation. Providing clean echo/delay times up to about 500ms and then noisier analog-esque delay times of up to approximately 800ms with modulation that goes from subtle tape-like flutters to seasick warbles, the Warble Swell Echo is sure to inspire.
