[5] In Summer 2007, following the departure of guitarist James Love from The Dillinger Escape Plan, Jeff Tuttle was the first person contacted by the band to fill-in because its bandleader Ben Weinman was "impressed with his drive" and work ethic since he toured with him.

Tuttle has made regular cameos in the web-based cooking show Solid Dudes Kitchen, created by his former bandmates in Heads Will Roll, Dave Graw and Derek Swanson.

In 2011, he founded the post-hardcore band Old Gods along with members of The Armed and Heads Will Roll, with him performing as the vocalist.
