The death of Phil Campbell triggered an outpouring of heartfelt tributes from rock stars worldwide.

Dee Snider, Duff McKagan, and Geezer Butler were among those who praised the longtime Motorhead guitarist as a gifted musician, humorous friend, and devoted father.

Campbell passed away on Friday night after what his family described as “a long and courageous battle in intensive care following a complex major operation.”

Born on May 7, 1961, in Pontypridd, Wales, Campbell joined Motorhead in 1984 and remained with the band until it disbanded after the death of frontman Lemmy Kilmister in 2015. His 31 years with the group were only surpassed by Kilmister.

His subsequent band, Phil Campbell and the Bastard Sons, was humorously named as it included his three sons: guitarist Todd, bassist Tyla, and drummer Dane.

“[We are] absolutely overwhelmed by the thousands of messages we have all received,” Tyla wrote in a social media post on Saturday. “Thank you from the bottom of our hearts. From old school friends I haven’t spoken to in years reminding me that Dad used to just stroll into the primary school hall and play some tunes on the piano before picking me up from school to absolute rock n roll and wrestling icons personally messaging me to say he was one of the best human beings they have ever met. He truly was. Little did we know that this would be our final Christmas together. I will love you forever Dad.”
