Ebony Archtop Bridge with Ebony Base and Metal Adjustable Thumbwheels Option:Chrome It has a cast aluminumThis ebony bridge will fit most archtop guitars and features and compensated wood saddle and chrome or gold thumbwheel and posts. The base of this bridge is extremely special as it's design utilizing two feet with a hollow bottom rather than a solid mount base, creating a self seating feature not found on other archtop bridges. This makes our AB 152 bridge a step above all the rest in ease of use and reliability. Important Measurements Mounting Base
