These reeds have their origin in old reed manufacturing technology where reeds are ground in the direction of rolling. This grinding is conducted on a single-purpose grinder. The tongues are ground individually. The tonal spectrum produced by this grinding procedure is different from that of reeds ground in the standard manner. Their technical features and specifications answer to the same standards as classic reeds. We offer this type of reed in A MANO NASTRINO, A MANO PROFESIONAL, and DIX.
