FT AcidTest regressive

FT AcidTest regressive font by Emil Bertell is a free groovy eroded display typeface that looks like it’s vibrating off the page. Heavy black shapes are carved into tight concentric rings, so every letter buzzes with a warped, psychedelic texture. The spacing stays surprisingly steady, which lets those rippling strokes feel wild without becoming unreadable, especially at big sizes.

Using FT AcidTest regressive, headlines feel like spinning vinyl or a flickering neon sign—loud, distorted, and full of character. This free font shines on gig posters, psychedelic album covers, festival branding, zines, experimental logos, and bold social graphics or merch. Pair it with a plain geometric sans in small text, and let AcidTest scream in oversized, high-contrast titles.
