Greetings from Adam Reiver! Welcome to FU-Tone website! (Formerly FloydUpgrades.com) FU does so much more than upgrade parts for “Floyds” and FU just seems so fitting for the circumstances of the name change! I have been working on improving tone with the greatest guitar players in the world for the last 25 years. I have found out what works and what does not… I am happy to share this with you. Tone is selective! FU is dedicated to help you find what is best for YOU! Using the best materials available, FU manufactures the ultimate in high performance guitar parts used by the PROS! Obviously, FU specializes in locking tremolo parts but if you dig around the site you will find upgrades for your Strat, Les Paul, Tele, Acoustic and more. In my dedicated effort to bring you the best of the best, I will continue to design and manufacture new FU products as well as bringing in other items that I think are cool. Check back often, feel free to ask me questions and keep chasing TONE!
