In January 1991, Kramer's exclusive distribution agreement with Rose ended when Fender announced they would be the new exclusive distributor of Floyd Rose products. While Fender used Floyd Rose-licensed vibrato systems previously, this move allowed Fender to offer a few models with the original Floyd Rose Tremolo, such as the Richie Sambora Signature Strat in 1991, the Floyd Rose Classic Stratocaster in 1992 and the Set-Neck Floyd Rose Strat in 1993. Floyd Rose collaborated with Fender to design a Fender Deluxe Locking Tremolo, introduced in 1991 on the Strat Plus Deluxe, the USA Contemporary Stratocaster, and the Strat Ultra. Fender used the Floyd Rose-designed locking vibrato system on certain humbucker-equipped American Deluxe and Showmaster models until 2007.
