Abstract

A golf club (40) having a club head (42) with a face component (60), an aft body (61), and a sound modifying component (59) is disclosed herein. The face component (60) has a striking plate portion (72) and a return portion (74). The aft-body (61) is composed of a crown portion (62), a sole portion (64) and optionally a ribbon section (90). The face component (60) is composed of a metal material, and the aft-body (61) is composed of a non-metal material such as a composite material or a thermoplastic material. The sound modifying component (59), which is attached to the metallic face component (60), alters the sound of the golf club head (42) when it impacts a golf ball.
