For reinforcing the bridge area, Maple or Rosewood bridge plates are used on steel string guitars underneath the soundboard, as illustrated. For classical guitars a bridge pad is often used, which adds stability and increases stiffness across the grain. Usually there is enough material left from the soundboard to make this pad, but should you run short we have made them available here.
Bridge “plates” are used on steel string guitars, bridge pads (made of top wood) are used on classical guitars. Most classicals require the 12” size.
