Further changes came to KLOS over the next year. On September 6, 2019, the station shifted its format to classic rock full-time, eliminating post-1990s modern rock tracks. On September 30 at 12:01 a.m., KLOS began broadcasting from its new studios at the Meruelo Media building in Burbank, leaving behind its previous location on Lindblade Street in Culver City (to which it and KABC relocated from their longtime La Cienega Boulevard studios in December 2016). The station also marked the return of the classic rock format to Los Angeles for the first time since KSWD flipped to the "K-Love" Christian music network in November 2017 as KKLQ. In late January 2020, KLOS switched back to mainstream rock and changed their slogan to "Southern California's Rock Station"; the station reintroduced post-1990s rock into the playlist while still maintaining a heavy focus on classic rock tracks. In a cost-cutting move prompted by the COVID-19 pandemic, Meruelo dismissed several members of the KLOS staff in mid-2020, including Frosty Stilwell, Gary Moore, and Frazer Smith; "Frosty, Heidi & Frank" reverted to its previous title "Heidi & Frank".
