This is a gold electric guitar-style hard-tail bridge, but made for 3-string cigar box guitars It took us a long time to find a source for these, but now we got ' These bridges are "top-loading" style, which means that the strings are fed through the back plate of the bridge, then up and over the saddles. No drilling through the instrument/box is required Each one is mounted securely by four screws, and a small Hex Wrench is also included for adjusting the small set screws that control string action height.
