The sweet sound of America’s most treasured and well-recognized tune is represented in this Amazing Grace Chime. The wooden parts are made of beautiful laminated bamboo, which is one of the most renewable materials on the planet. Consumer warranty is 1 year for anything, lifetime on tuning. Chime tubes are 3/4 inch in diameter and 25 inches in height (from hanger to clapper). When listening to a Woodstock Chime, you hear a perfectly tuned musical instrument, played by the wind. Since 1979, GRAMMY award-winning musician and instrument designer Garry Kvistad has tuned each chime based on famous melodies and scales heard around the world. Each chime has its own “voice” that contributes to a mood or atmosphere. In Use Dimensions (inch): 25.00L x 5.25W x 5.25H
