This shimmer effect is a combination of effects that creates an etherial wall of sound. The effect combines a digital delay and pitch shifter to create multiple harmonies before entering a rich long reverb with controllable filtering. The resulting effect is a monsterously huge sound adding a spacious atmospheric quality to any lead instrument or vocal.
