Swell Shaper

Electro-Harmonix takes one of the best-loved features of its POG2 and puts it into a standalone pedal

- Trevor Curwen

First seen in the POG2, the Attack slider is a feature that has particularly hit the spot with players, adjusting the note envelope for swelled or bowed sounds whether or not you're using the pitch aspects of the pedal. Now, that specific effect has been made more accessible to all in a dedicated pedal in Electro-Harmonix's diminutive Pico range. The Swello is designed to slow the volume envelope of your playing to create swells, something it does polyphonically, so chords as well as single notes get the full treatment. It also has an optional low-pass filter that can be used for polyphonic envelope filter effects.
