: so please tell me something that can help to stop this.
: my question is :
: 1. The soundpost's right position.
: 2. Does your soundpost usually sink ?
RE: Uh oh, you have problems. If you do not have the proper soundpost setting equipment, it is very difficult to put the sound post back in place. Take it to
a repair shop,but if you can't, well..I do not reccomend you do this yourself if you have never done it before, but here is the answer to your question...
The soundpost should be about 20-25 mm (almost 1 inch) below the foot of the bridge on the G string side and it must make full contact with the top and bottom plates.You need a small mirror to see if the top of the soundpost is even (making full contact)with the top of the Bass. By the way, you should do this with the strings loose, and then tighten them after you get the sound post set up.
This will keep your soundpost from sinking.No, soundpost usually do not sink unless they are not properly installed, or if you loosen all the stings at once.I hope you can get it fixed. Good Luck!
