While surfing the internets, I found this list of drummer jokes that someone has maliciously edited into bass player jokes. These are the worst ones. This is not funny at all. This is the sort of thing that gives guitarists a bad name.
Q: How many bass players does it take to change a light bulb? A: Only one - but the guitarist has to show him first.
The key is the shallow angle between the saddle and the string. A proper guitar bridge has a sharp break between the saddle and the string. This shallow angle causes the classic sitar buzz. This is a very easy part to make from any decently hard wood. A scrap of fretboard blank is ideal. A little experimenting, and you will get it. Then you can convert any guitar into a "sitar".
