- "Their [the brothers Amati] viola da gamba of the year 1611 embodies diverse traits which became standard in the double bass maker's vocabulary during the late 17th and 18th centuries: the round back with bevel, the gently sloping shoulders, and the ribs which diminish from the endpin to the neck block (gi. 10-11). This form is actually a composite, in part derived from earlier viols and partly their own innovations, but in any case, quite original, well composed, and beautifully synthesized."

- "The famous Karr-Koussevitzky double bass, once attributed to the Amati Brothers and built ca. 1611, was likely built by French luthiers in the late 1700s."
