The Qwistle version 1.0 is a penny whistle with a sweet, focused tone, moderate volume, clear but sweet bottom hand, easy octave crossing, sweet high notes and a well-tempered scale throughout.

Developed specifically as a 3D printed musical instrument, the Qwistle is produced using Selective Laser Sintering, and is then hand finished and dyed at Lindstruments' workshop in Glasgow, Scotland.
