Paul McCartney's favorite guitar reached a whopping value decades after the singer bought it.

The Beatles member first had his Hofner 500/1 electric bass after purchasing one in a shop in Hamburg in 1961 for $32. He notably used it to play "Love Me Do," "Twist and Shout" and "She Loves You."

Decades after it disappeared, experts said the instrument could be worth millions once found.

Paul McCartney's Hofner 500/1 Electric Bass Could Be Worth Millions Now

McCartney is said to have launched a worldwide search to reunite with his beloved instrument after letting it go in the 1960s. His office reportedly told the manufacturers that he wanted to hold it again now.

Hofner executive Nick Wass, who has been in contact with the office, said the musician asked him if he could help him find the bass.

"That's what sparked this great hunt," Wass said, per Express. "Seeing what the lost bass means to Paul, I was determined to solve the mystery. For most people, they will remember it. It's the bass that made the Beatles."

The search led the hashtag #tracingthebass to trend on X, formerly Twitter, to find the multimillion-worth instrument or at least trace its whereabouts.

Paul McCartney Honors Late Singer Jimmy Buffett

In other news, McCartney recently shared his heartbreak and joined the long list of people who paid tribute to Jimmy Buffett, who died of Merkel cell skin cancer. The late singer reportedly fought the disease privately until he died at the age of 76 at his Sag Harbor, New York, home.

Buffett sparked concerns in the months leading to his death due to his constant hospitalizations, which led to the cancelation of his shows.

McCartney shared a photo of himself with Buffett alongside a lengthy message to honor his life and career.

"It seems that so many wonderful people are leaving this world, and now Jimmy Buffett is one of them. I've known Jimmy for some time and found him to be one of the kindest and most generous people," the beginning of the message read.

McCartney confirmed that he was part of Buffett's new song, "My Gummy Just Kicked In," which would be released posthumously on September 8.

Buffett's family asked fans that, instead of flowers, they could donate to the musician's Foundation Singing for Change, Brigham and Women's Hospital, Dana Farber Cancer Institute or the MD Anderson Cancer Center instead.
