Mattoverse Warble Swell Echo MkII

An original design, the Mattoverse Warble Swell Echo MkII is an unusual take on the lo-fi, modulated echo by a manufacturer who has demonstrated a special and consistent interest in creative and quirky circuits.

It’s a vintage-voiced echo/delay with a dynamic foot-controllable Swell feature and gooey tape-like modulation. It provides echo/delay times that range from short clean slapbacks to long (up to 800ms) warm analog-esque repeats. The onset of the Swell effect can also be controlled through a separate knob.

A rotary Wave knob selects between 8 shapes for the modulation’s LFO. This section can deliver anything from subtle tape-like flutters to seasick warbles to random madness.

MkII delivers the same goodness features in the original, in a smaller, compact enclosure, with the added bonus of the 8 modulation waves, not available in MkI.

We added the Mattoverse Warble Swell Echo MkII to our article about the best creative delay pedals.

We had the honor to shoot the first video of the Warble Swell Echo directly at our our NAMM 2018 Pedal Demo Marathon (all videos of new pedals released at NAMM can be found here).
