ZS70 "Bendeguz" Doromb
ZS70 "Bendeguz" jaw harp with a second type of the reed, used by Hungarian master: those are harder and giving different sound character. First of all, reed mechanics allowing much more stroke techniques - inharmonious extra sounds are barely noticeable at outwards stroke and pressing force controlled more precisely. Gaps/overtones evenness is the same lottery, as for any ZS doromb - it can be perfect... or not. At least, sound volume/sensitivity is from good to high in most cases, though frankly muffled exemplars can be found too. Round elbow tip can be present or not - it is just a tuning weight, not part of geometry. Any doromb has scratching square tip as basis.
