The most underdeveloped and overlooked part on a double bass drum pedal is often the linkage. Weak joints and low tolerances eventually lead to a weak response from your secondary pedal. Now you can upgrade your favorite double pedal with a Trick P1V6 Drive Shaft. Its unparalleled performance stems from our aluminum shaft outfitted with two of our patented ZERO-latency, ZERO-backlash, free-floating universal joints. Each joint utilizes four roller bearings with precision-ground press-fit pins in an ultra-light aluminum cage. This revolutionary design ensures your secondary foot gets the same accuracy and power as your primary foot. Length Range: 16" - 24.75"
