Mattoverse Electronics Warble Swell Echo

Mattoverse Electronics Warble Swell Echo


The brand new Warble Swell Echo from Mattoverse Electronics is an analog voiced digital echo/delay with a dynamic foot-controllable Swell feature and gooey tape like modulation. Providing echo/delay times that range from short clean slapbacks to approximately 800ms of warm analog-esque repeats with modulation that goes from subtle tape like flutters to seasick warbles, the Warble Swell Echo is sure to inspire.

Note: The current smaller format version is the same circuit as the previous larger format version, will only be making this smaller format version going forward.
