The bass type, similarly to the theorbo and other baroque lutes, has a vaulted body (shell) constructed of separate ribs, a flat soundboard with either a carved rose or one which is inset into the soundhole, and a bridge (without a saddle) consisting of a wooden bar acting as a string-holder glued to the soundboard. Unique to this instrument is the neck, which is long enough to allow for ten to 12 tied gut frets. The pegbox is either straight and set at a sharp angle to the neck (much like a lute pegbox), or gently curving and set at a shallow angle, either case being fitted with laterally-inserted tuning pegs (although sometimes a flat pegboard with sagittal pegs is found). The strings were of gut and are strung either singly or, especially on Italian instruments, in double courses. However, on German-made instruments, the first course (highest in pitch) is usually single (a chanterelle) and often has its own separate raised peg rider/holder attached to the pegbox. The number of courses varies from six to eight. Open string lengths tend to be fairly long (62–72 cm) on German instruments, but shorter (55–65 cm) on late Italian ones, probably because they tended to be tuned to a higher pitch.
