Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Electro-Harmonix Pico Swello is a compact auto swell pedal that slows the volume envelope of your playing to create smooth volume swells, working polyphonically so chords as well as single notes swell fully. Beyond classic violin like swells, it can generate envelope filter and wah like textures, big synth style pads, and even act like a compressor to soften picking irregularities. With simple controls in a tiny enclosure, it delivers expressive, ambient swell effects effortlessly. It suits ambient, post rock, cinematic and pedal steel style players who want hands free polyphonic volume swells, pad textures and attack smoothing in a space saving pedal without manually working a volume pedal.
The Keeley Neutrino V2 is a compact, all-analog opto-coupler envelope filter and auto-wah that creates a touch-sensitive wah sound from your pick attack. Hand-selected opto-couplers, described as higher grade than those in vintage originals, give it a smooth, vowel-like, vocal tone. It offers three filter ranges, two sweep directions, two frequency-center ranges, and a Peak control for shaping resonance, with true bypass to avoid tone suck. It suits funk, fusion, and expressive playing where dynamic filter movement adds vocal character to lines. Simple to dial in for a satisfying auto-wah, it is a small, focused envelope filter, though some players find its output can sound thinner than they expect at certain settings.
