Madison Cunningham demonstrates how she uses a slow, low-depth vibrato as a permanent layer in her guitar tone, kept so subtle it registers more as a feeling than an effect.
In a live band context with guitar, bass, drums, and keys, that constant pitch movement adds dimension and makes the guitar sit bigger in the mix without drawing attention to itself.
The pedal's second preset runs faster and deeper, tipping into Leslie-like territory, and Cunningham reaches for it when a part simply calls for that more intense character.
But switching into it mid-song also does something compositionally. Riding the subtle setting through a verse and then hitting the heavier one at the bridge creates an immediate sense of scene change, mapping modulation speed and depth onto the dynamic arc of the song.
