VANSON 'ABR1' Bridge.
Precision engineered, with high quality plating you get a lot more for your money than the price-point infers. To avoid the problematic rattle of the 70's retaining wire versions, these have a High-stability 'E' ring, which performs brilliantly.
Please Note:
Also, on US Spec guitars, please check you do not have a Nashville style post set-up where the base of the post is wider than the top. These posts are the same diameter all the way down.
