Kohinoor Surbahar
The sympathetic strings pass over the smaller bridge which is directly glued on the tabli. The bridges have a slightly curved upper surface parallel to the string that the strings touch when vibrating, which results in a buzzing sound known as jawari.
It differs in that most surbahars have a gourd that is larger and tilted 90º so that the bottom of the gourd is to the back of the instrument, creating a shallower and rounder body for an enhanced bass response.
