Having an exceptional flair for novelty, Prattyush has remodeled the traditional sarode to a great extent, as explained in details here.
He has considerably reduced the width of the fingerplate on his sarode, which at its widest point (at the juncture of joining with the drum) is only 4.5". He also uses a stainless steel maintenance-free fingerplate.
The air-chamber that extends like a hump to approximately half the length on the traditional sarode is much shorter on his instrument - where it only extends to approximately 4" from the drum juncture.
Both of the above changes not only make his sarode more streamlined and lighter but also facilitate better grip of the left hand on all the strings for high notes.
He has replaced the traditional bone bridge with one made of ebony.
The bone-made chikari bridge is also replaced with a metal pole riveted to the fingerplate - thereby doing away with screws on the body and also minute wavering that may disturb the sound of the chikari after a few years.
