A small jews harp with a loud, crackling, saturated sound in the slightly above average range. The mechanics of the reed have only one way to strike - otherwise, if you do not play only at the maximum volume, there are uncontrollable bursts, and a outwards stroke generates constant out-of-the-ordinary sounds. An excellent instrument for punching through noise without much expense and simple rhythms - the sound is easily issued. Supersaturation masks most overtones in the controllable range.
