Electro Harmonix Pico Swello Attack Envelope

The Electro-Harmonix Pico Swello builds upon the legendary POG2, one of the brand's most popular effects, and offers a unique twist on the renowned polyphonic attack filter technology. This effect adjusts the attack of every note or chord, creating a rich, multi-layered sound that adapts effortlessly to your playing style. Whether you are playing complex arpeggios or creating dramatic swelling sounds, the Pico Swello gives you the musical flexibility to produce both subtle and expressive textures. The polyphonic attack filter forms the heart of this pedal and makes it suitable for a wide variety of musical styles.

Pico Swello: Simple operation

With four simple knobs, you can easily customize the Pico Swello to your liking. The ATTACK control is the key to determining the pedal's attack time, from fast and subtle to slow and dramatic. The VOL knob allows you to fine-tune the effect's volume exactly to your liking, even with longer attack effects that might otherwise reduce the volume. The FILTER, FREQ, and MOD knobs give you the ability to modulate the low-pass filter and vary the effect from a soft swell to a powerful, synth-like sound, depending on your preference.
