Very straightforward.
Go to "Customise Your MyPLAYER" and go to Golf Bag. You just have to equip or buy clubs from five of the six different bands available (Callaway, TaylorMade, Bridgestone, Ben Hogan, Wilson, The Golf Club).
You spread these across the various club types (Drivers, Woods, Hybrids, Irons, Wedges and Putters). The achievement will pop when you complete the full 18-hole round.
