Jiva Jive - Adding threads to strings on a cigar box tanpura. 4K

How do you get that buzzy, drone, overtone sound from a cigar box tanpura?
Add threads between the strings and bridge, and move them until you get the best, sustained buzzy, droney note.
it's a trial and error process. a tiny adjustment makes a huge difference, thread thickness too... I.m still experimenting, but it's close...
