“Often times in the studio I'll create new guitar textures by combining various stomp boxes and delay effects with manipulative recording techniques and harmony layers resulting in some pretty complex tones. Amazingly, each one of the Eventide units that have resided in my various touring rigs throughout the years, is able to easily and faithfully recreate those crazy experimental guitar sounds and successfully bring them to the live stage night after night! It really is a fantastic creative tool. ” Also, below the quote, there is ModFactor model linked to him.

In this article Rob Laakso, Kurt Vile's bandmate and engineer on the Album B'lieve I'm Going Down, says: “One thing was definitely handy for the pitch vibrato that Kurt wanted on the clean guitars,” he recalls. “We weren’t hauling our own amps around, so I was able to cobble together a pretty decent one out of the Eventide ModFactor. I remember at one studio, there was a Watkins Tremolo amp that we were all excited to use, but it made a horrible humming sound and wasn’t working right. Then across the room they had a Gibson stereo tube amp and that wasn’t working right either, so I busted out the Eventide and had a pitch vibrato that made everyone happy. That definitely appears on the record—almost any pitch vibrato you hear on the album, it’s probably that.”
