Abstract: A golf putter having a head with an opening. The lower end of the putter's shaft has a bushing received in the opening. A slug having a multi-faced mid-section is received in a central opening in the bushing. The slug has shoulders connected to the head in such a way that the angle of the shaft with respect to the head depends upon the slug configuration. One version employs a club head with a longitudinal channel for supporting the lower end of the shaft in an adjusted position. The shoulders on the slug that seat in the sides of the channel. Another version employs a club head with a back opening for receiving the slug. The shaft has a pair of telescopically connected sections that can be incrementally adjusted to change the shaft length. An auxiliary shaft can be added to increase the overall length of the shaft.
