in 2007 Bernwall was born in
Fagersta and began playing bass in bands while still in
mellanstadiet (compulsory schooling in Sweden). The Hives were formed in 1993, when he was 15 years old, and rose to prominence in the early 2000s as a leading group of the
post-punk revival, playing
garage rock. Bernwall typically played a 1970s
Fender Telecaster Bass which differs from the late-1960s Telecaster and 1950s Precision bass (each inspiring another) in that it has a
humbucker rather than a single coil pickup. His bass was in the band's signature white/black color combo along with a white
Hiwatt amplifier; he almost always used bass
distortion and a
pick. He also occasionally played a
Rickenbacker bass, as seen in the "
Hate to Say I Told You So"
music video. Bernwall departed the Hives in 2013, for undisclosed health issues. He made a cameo appearance in the band's 2023 music video for the single "Countdown to Shutdown". During a show in Stockholm in December 2025, Bernwall was brought onstage by the band and played several songs. ==Discography==
