With their tight thread spacing and careful manufacture, PDP/DW's proprietary True-Pitch 32 tension rods give you exacting tuning control and precise intonation. True-Pitch tension rods are a direct replacement for modern PDP shells and most DW Design and Performance Series kits. Whether as part of a regular tuneup regimen or a safeguard against losing screws in the studio or out on the road, PDP True-Pitch tension rods are the smart way to keep your PDP and DW drums playing and sounding at their peak.
