A golf club shaft is disclosed. The shaft includes a tip section, lower section, and an upper section. The tip section connects with a golf club head. The lower section includes a tapered section and a reverse taper section. The tapered section extends from the tip section. The tapered section increases in diameter in a direction away from the tip section. The reverse taper section extends between the tapered section and the upper section. The reverse taper section has a diameter that decreases in a direction away from the tip section. The shaft further includes a resilient plug wedged inside the shaft. The plug extends along the reverse taper section, the plug being formed from a sound absorbing material.

[ What is claimed is:] [1.] A set of a plurality of golf club shafts, with the length of each shaft from a tip end to a butt end decreasing along the set, each shaft comprising:a) a tip section for connecting with a golf club head, said tip section extending from the tip end of the shaft;b) a lower section including a first tapered section and a reverse taper section, said first tapered section tapering from the reverse taper section toward said tip section, said reverse taper section tapering from the first tapered section toward the butt end and being at a distance from said tip end;c) an upper section including a grip section extending from the butt end to a second tapered section, the second tapered section tapering from the grip section and ending in the reverse taper section at a substantially constant taper rate; andd) the distance from the tip end to the reverse taper section of each shaft varying from shaft to shaft along at least a portion of the set as the shaft length along the set decreases; wherein the first taper section has a first taper per unit length and the second taper section has a second taper per unit length, and the first taper per unit length is greater than the second taper per unit length so that the stiffness of the lower section is greater than the stiffness of the upper section.
