Born circa. 1640, died 1713 Bologna Italy. Son of Gaspare, a ‘case-maker’. Active from 1688. Very fine and distinguished work, although quite variable. It is probable that alongside his son Carlo, Guidanti may have participated in the workshop. Amati model, some with quite dished edges and medium height of arch. Slightly boxy in the Stainer manner; others of generally fuller modelling. The heads are distinctive with the volute rather small and cramped, especially on the cellos. Some have a broad and well-handled chamfer; others a less confident line. The soundholes are well cut and open with slender slightly pointed wings, possibly set a little close together.
