Professional Buzz Stop (Chrome) &ndash; Fits Fender Jazzmaster & Jaguar Guitars &ndash; Buzzstop Supports Tremolo IMPROVES SUSTAIN: The Buzz Stop creates a sharper downward angle on the strings to increase sustain and keep them from sliding on the bridge saddles. REDUCE BUZZING & RATTLING: Downward string pressure helps reduce excess buzzing and rattling often associated with these musical instruments. WORKS WITH TREMOLO: Strings pass under a rotating roller pivoting smoothly on two stainless steel pins, leaving the tremolo completely unaffected. EASY INSTALLATION: Dont worry about adding screws to your guitar. Simply locate the unit and add the buzz stop with the two existing screws already there. SATISFACTION GUARANTEE: We promise you a high-quality product, which is why our Buzz Stop comes with a 30-day money back guarantee and a manufacturers warranty.
