DXTRND. Traditional improved Whistle with Nickel body. Fully tuneable whistle in High D. This trad whistle has been improved over the regular nickle whistles. The main advantage over other nickle whistles is that this is tunable and clear on the high notes. Very popular whistles among Comhaltas students esp great for reels. It achieves a very high quality sound. Definitely one of my favorites. Also available in the Key of E.
