The bridge slopes upward toward the bridge pins and moving the saddle back will raise the action significantly. In order to keep the action close to the original action I sanded the bridge until the location for the new slot is the same height as the old area. This made the bridge flatter than original but the lower pin location will also help create a better break angle over the saddle. After leveling the bridge I reinstalled the “intonator” and marked the correct location for the new saddle. I then routed the new saddle slot with a Foredom router attatched to a homemade slot cutting jig.
