Abstract
A wood-type golf club head (40) having a major body (50), a striking plate insert (55) and a minor body (60) is disclosed herein. The major body (50) is composed of a metal material and has a front wall section (72), a return section (74), a sole section (76), a ribbon section (78) and a ledge portion (80). The minor body (50) is preferably composed of a low density material and has a crown section (62) and a ribbon section (64). The striking plate insert (55) is composed of a metal material. An epoxy-based composition (200) is placed at a face-sole junction (205) to lower the amplitude of the sound of the golf club head (40) during impact with a golf ball.
