The practice whistle has been redesigned to make the Bingamon Low-D Plastic Whistle. It’s just a little more than the original practice whistle but plays 40% longer in a single breath.
Also, the Basswhistle is out. Low-Low-D with 6 toneholes. The new style keys used on the basswhistle close at an angle to allow ornamentation using keys. With the size of these keys, it doesn’t matter whether you use pipers fingering or fingertip - you’ll cover it.
