Derived from the legendary POG2, the EHX Pico Swello brings you its unique attack filter, applying an attack envelope to each individual note played—whether you're playing single notes or full chords. This creates a highly musical, multi-voice effect that adapts beautifully to any musical style. The polyphonic attack filter is the beating heart of the Pico Swello, generating lush swells and reverse sounds with the added bonus of a modulated low-pass filter for even more expressive, synth-like tones.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan class=\"\"\u003eWhy Choose the Electro-Harmonix Pico Swello?\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan class=\"\"\u003eStandalone POG2 Magic:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan class=\"\"\u003e You no longer need a massive POG2 to get that famous, lush attack envelope effect.
