Action adjustment system

An important problem on almost all Ouds is that the neck rises up after a couple of years due to strings' tension which increases the depth of the gap between strings and the finger board. This causes some critical problems:
1- The oudist will have to put more pressure on the strings while fingering. This will cause more pain on the finger tips and make the oudist tired more quickly.
2- The extra pressure causes false notes.
3- This will make it harder for the oudist to perform the techniques correctly.

Moreover, different oudists prefer different actions according to their playing styles. So the luthiers have to make low action or high action Ouds according to their order. Adjusting the action in other instruments is done by changing the top skin (instruments like the Tar and the Kamancheh) or changing the saddle (instruments like Setar or Santour).

Action adjustment system is designed so that the oudist can easily adjust the neck for his desired action. This is done by a number 6 allen screw which is installed on the bowl near the neck and it's not needed to adjust the neck from inside the bowl. This system can be used in all Ouds (with or without rossetes) and similar instruments.
