Electro-Harmonix Pico Swello Digital Attack Envelope

Electro-Harmonix Pico Swello Digital Attack Envelope

The Electro-Harmonix Pico Swello is a compact powerhouse that brings the beloved POG2 attack envelope into its own pedal. Its polyphonic attack filter applies smooth swells to each note, perfect for lush chords or single-note runs. The intuitive 4-knob layout gives full control over attack speed, overall volume, low-pass filter cutoff, and modulation depth. Use subtle settings for a natural, flowing attack or crank it up for dramatic, ambient swells and synth-like textures. The modulated low-pass filter adds extra movement, making this pedal a perfect tool for ambient, experimental, and textural players. At Riffs & Licks Music, we think this is an inspiring pedal for anyone looking to add cinematic dynamics and expressive movement to their sound.
