A Gamba stop pitched an octave lower than normal, at 16' (manuals) or 32' (pedal). According to Hopkins & Rimbault, it was frequently used by Henry Willis. Irwin describes its tone as �rich, brilliant, but not especially loud�; Audsley calls it �string-like ... but not so pronounced as to be imitative�. According to Audsley, it is constructed from cylindrical open metal pipes of medium scale. The name Contre Gambe does not appear in the literature, but we assume it to be a synonym. Irwin alone lists Grossgamba as a synonym, but other information shows it to be a different stop; see Grossgamba.
Osiris contains about six dozen examples. All are at 16' pitch except for three at 32' pitch, of which 2 are electronic.
