In a previous video I removed a standard 6 string through the soundhole bridge. The old one was loose and I could either glue it back on after removal, or replace it with another bridge. In this case a new bridge was carved to replace the old one, in particular the new bridge is constructed similar to an Ovation® style bridge. The strings go through the back of the bridge rather than through the soundhole. I used dowels and the one and six string holes to help register and anchor the new bridge.
