Gene Simmons and Paul Stanley have described Ace Frehley as an "irreplaceable rock soldier" following his death, aged 74.

The two KISS guitarists have led tributes to their late bandmate - who died on Thursday (10.16.25), following a recent fall at his home - admitting they have been left "devastated" by his passing.

Gene and Paul wrote in a joint statement shared with The Hollywood Reporter: "I am devastated by the passing of Ace Frehley.

"He was an essential and irreplaceable rock soldier during some of the most formative foundational chapters of the band and its history.

"He is and will always be a part of KISS's legacy. My thoughts are with Jeanette, Monique and all those who loved him, including our fans around the world."

KISS founding member Peter Criss wrote on X: "I'm shocked!!!

My friend... I love you!

Several other stars from the world of music also paid tribute to Ace, including Poison frontman Bret Michaels.

He wrote on Instagram: "Ace, my brother, I surely cannot thank you enough for the years of great music, the many festivals we've done together and your lead guitar on Nothing But A Good Time. All my love and respect, from my family and myself - may you rest in peace!!! (sic)"

Rage Against The Machine's Tom Morello described Ace as his "first guitar hero".

He wrote: "My first guitar hero, Ace Frehley, has passed away. The legendary Space Ace Frehley inspired generations to love rock n roll and love rock n roll guitar playing. His timeless riffs and solos, the billowing smoke coming from his Les Paul, the rockets shooting from his headstock, his cool spacey onstage wobble and his unforgettable crazy laugh will be missed but will never be forgotten. Thank you, Ace for a lifetime of great music and memories."
