The Dunbar Large practice chanter is a high quality practice chanter with a nice tone. The long length practice chanter has the same hole spacing as the highland bagpipe chanter. The chanters are made from Polypenco. The Dunbar practice chanter has o-rings for the seal between the top and the bottom pieces instead of using hemp. This gives an airtight, maintenance free seal. All practice chanters have counter sunk holes and come with a practice chanter reed.
