Casale worked on a solo project called Jihad Jerry & the Evildoers that included pre-Devo guitarist Peter Gregg. He also has recently worked on a Devo biopic and a Devo musical (but both projects unfunded). He is currently active on twitter, and often follows back fans who follow him.
Gerald Casale uses a right-handed Steinberger L-Series bass guitar, played upside down.
Outside of Devo, Casale developed friendships with up-and-coming Los Angeles chefs, an interest in fine cuisine, and in pairing foods with fine wines. With business partners, he has filed a patent for a type of wine rack and much later launched a private label wine. He fully restored a Richard Neutra house before selling it and built the previously unrealized 50' by 50' house from the plans drawn by Mies Van Der Rohe. It is used as a wine tasting room.
Gerald and his wife Krista have an awareness of and an interest in reducing animal cruelty. PeTA approached Casale to direct an awareness video with footage of the treatment of performance animals. Casale attended a PeTA 25th anniversary event. He enlisted his band-members to make the song "Don't Roof Rack Me, Bro! (Seamus Unleashed)" about a political candidates' treatment of the family dog. He approached his band-mates to approve giving royalties from the song "Whip It" to PeTA on a campaign for circuses to end their abusive behavior by sending their big cats to wildlife preserves.

- ↑ People for the Ethical Treatment of Animals (PeTA). Drop That Whip: Devo Gets Behind Push to Free Big Cats From Circuses by Craig Shapiro. March 3, 2016 press release. Says the band: “As Ringling Bros. relies on the fear of whips to force lions and tigers to perform, Devo is pleased to make a grant to PETA from the royalties of ‘Whip It’ for their campaign to free big cats from this abuse. We hope that all circuses will continue to evolve by spotlighting human creativity rather than degrading animals.”
