Electro-Harmonic Pico Swello
The Electro-Harmonix Pico Swello is a compact, digital attack envelope pedal designed to create polyphonic volume swells, mimicking the effect of bowed instruments like a cello. Inspired by the attack slider on the POG2, the pedal applies individual volume swells to each note, allowing for smooth, bowed-like blooms even within chords and sustained arpeggios. It features controls for Volume, Attack (which sets the swell time), Frequency, and Mod. A dedicated Filter button engages an adjustable Low Pass Filter (LPF) with resonance, adding sonic potential and allowing for smooth swells or envelope filter-style effects. The Mod knob controls the depth and direction of the filter modulation. Housed in EHX's Pico-sized chassis, the Swello uses buffered bypass and is powered by a 9V DC supply. It is ideal for players seeking a unique, expressive modulation effect.
