ZS90 "Evagelist" jews harp with a moderately soft reed and loud, bright sound (possible pitches range among exemplars is higher than ZS average). Gaps are small and sensitivity is high - lightest touch giving distinctive result without efforts. Mechanic properties are not the best - elbow/knee is soft, moving in separate directions with intensive strikes, adding various vibrations - that player will hear and feel by finger. Any speed can be achieved but sound cleanness will be sacrificed proportionally. Reed tip is unfinished and can scratch finger. Randomly it can be weightened with tin, or copper wire. Size, pitch, gaps, volume and other acoustic properties can be considerably different from exemplar to exemplar. The frame is extremely thin and easily squeezed under uncontrolled grip, yielding clanging. Overal character is lively - beginners will have many hours of pleasure playing this jews harp. Good for percussive style without using clean overtones.
