Seller’s site says the $5 million sale is for the Fender Special Edition model of the popular Fender Stratocaster electric guitar, which is made by Gibson.
The seller says it sold it to a Chinese company.
A Gibson spokesman declined to comment.
The sale is the second time the Fenders have made headlines for selling to a new, non-Gibson owner.
Last year, the company bought the Stratocasters of Chris Martin and Mark Wood from the Gibson family for $5,700 each.
The company also bought the Gibson Les Pauls, which have been the signature guitar of guitarist Jimmy Page.
