Eventide ShimmerVerb combines a massively lustrous reverb with parallel pitch shifters to add ethereal layers making any signal, well, "shimmer." Oftentimes, producers would achieve the effect by using Eventide pitch shifting hardware such as the H910, H949, H3000 or other rackmount units in combination with a reverb. This production technique was popularized by Daniel Lanois and Brian Eno on U2's The Unforgettable Fire. Now, this iconic sound has been refined and extended with a modern, unified interface that is great for adding dreamy ambiance to guitars, keys, synths, samples and vocals. In typical Eventide fashion, features have been added such as the ability to infinitely feedback the signal, resulting in cascading reverbs that smear into oblivion. Feedback can be further fine-tuned by specifying which frequencies are fed back through the low/mid/high cross-over network.

ShimmerVerb shines via its playable, performance-based parameters. THE RIBBON is an easy-to-program performance macro, allowing users to morph between two settings with one control. Desktop users can plug in a MIDI keyboard and gain tactile command over this function via the modulation wheel. Ribbon mappings are great for feedback swells, moving the pitch knobs, or changing the size for a massive detuning result. ShimmerVerb also boasts a HOTSWITCH for calling up another state of parameters inside the same preset. Use this for changing octaves, turning off/on the pitch shifters or simply turning the mix up or down while crafting your performance. Finally, the FREEZE button allows you to make smeared textures out of single voices, full pads or percussive elements resulting in metallic shimmers.
