Jerry Freeman is the world's only full time, professional penny whistle
tweaker. "Tweaking" a penny whistle is much like setting up a guitar or fiddle; it is the process of making fine adjustments and modifications to get the best possible performance from the instrument.

Jerry takes mass produced whistles (Generations, Feadogs, etc.) and adjusts the soundblade position, windway exit geometry, voicing chamber and tonebody to create affordable instruments that many consider not simply outstanding whistles for the modest cost, but outstanding whistles at any cost.

Jerry offers tweaked Generations in high G, high F, Eb, D, C and Bb, tweaked Feadogs in D, and his own creations, the widely acclaimed Blackbirds and Mellow Dogs.

Mellow Dogs are wide body whistles available in D and as a D/C set (one whistlehead with two tubes). Blackbirds are standard body whistles available in Eb, D and C. Both are noted for their pure drop authentic traditional voicings that favor a birdlike, sweet timbre in a very responsive, clean playing instrument.
