MONTREUX's wrap-around type compensated bridge for guitars, also known as a "Lightning" bridge. This bridge offers improved intonation compared to a bar bridge. It fit the user's Gibson USA guitar. It was used without notching the bridge, so there are only slight string marks on the string contact points. Studs are not included. Everything in the photos is what you will receive. Please understand that this is a used item and is sold as-is, with no returns. Unfortunately, I am unable to offer a discount. ~From the seller's website~ ■ For guitars with a plain 3rd string ■ Compensated bridge ■ Material: Zinc die-cast ■ Nickel color ■ Dimensions ・Stud pitch: Approximately 82.5mm ・Adjustment screw diameter: #6-32 Length: Approximately 9.4mm Adjust with a 1/16" wrench
