My Bloody Valentine experimented with a noise pop sound on the album, a venture which was influenced by The Jesus and Mary Chain, and incorporated elements of twee pop similar to "Strawberry Wine". Shields used a twelve-string electric guitar during the "Ecstasy"s recording sessions and was influenced by The Byrds during the writing process, which resulted in the guitar tones being "too jingly jangly". Writer Colin Larkin described "Ecstasy"s sound as "bubblegum pop with buzzsaw guitars", which was similar to their prior releases and further diverged from their earlier post-punk and gothic rock sound. Jim DeRogatis noted that "Ecstasy"s overall sound "ushered in a sunnier, more optimistic vibe" for the band which was reminiscent of the sound of 1960s American psychedelia, in particular the Los Angeles based band Love. "Clair", one of the first recordings to feature Bilinda Butcher, features a sampled tape loop of audience screams from The Beatles live album, "The Beatles at the Hollywood Bowl" (1977). The sample was processed through audio filters to emulate guitar feedback.
