Sound posts don't have their ends cut perpendicularly. They are shaped for the top and back (assuming a roundback). Your sound post has been cut and shaped for a particular location and a small variance around that location. A considerable amount of expertise is required to reset it making sure it is flush. That also requires being able to see the fit. Listen to T-Bird. Unless you have a plywood bass that you don't care about damaging, get thee to a luthier! :)

Why did you even post on here? If all you want is to be told what you want to hear. The best answer to your question is "your luthier knows best" is a fine answer. You obviously don't know how to change the strings on the bass, if you did you would know you change them one at a time TO AVOID THE DAMN SOUNDPOST FROM FALLING DOWN! If you go to a good Luthier, they might not even charge you or charge very little depending on how much of a job it turns out to be.

If the soundpost is properly fitted for the position that it is in it won't fall down if you remove the tension from all the strings.

"Luthier knows best" works up to a point, I actually have to bring my bass back to have the post repositioned since I'm not getting enough volume playing jazz pizz out of the low E, my new luthier thought I just played classical, it sounds fine arco.

Only to a point, (from what I've been told) that the post should stay up without string tension, but should be able to fall when the strings are off.

Why don't you just adjust the post yourself? You just said the Luthier isn't always right.

If I had a cheaper bass I would try...somewhat...maybe. He knows what he's doing when it comes to positioning it(I would be trial and error, I don't have time for that) and I don't have to pay for it, also I don't have that nifty tool.

And no, it shouldn't fall if you take the strings off and it is in proper position/is the proper length/etc.

No Dave, this is not a hard and fast rule. When I've had my bass at my luthier and he pulled all the strings off for this reason or that, my soundpost did not fall. Still, it is quite possible to have a carved bass worked on during the summer months and have the sound post drop if all the strings are off and it gets bumped just a bit. If it falls under such circumstances, it's not necessarily indicative of an improper fit.

Hosking thankfully posted the link that addresses the issues involved. The real question is if brahmshalim is still paying attention to this post, and if so, if he should attempt it himself or pay the $20 to get a pro to do it...which might take a week or more this time of year, if there is even one close to wherever he is located. I say if he has a cheap plywood and has the tools to do it then why not, if he wants to be playing on it right now. If he can wait, then taking it to a luthier seems the best option.

Look inside the bass, there should be very faint marks/indents on the top and back where the sound post originally was.
That's as good a place to start as any.

You absolutely have to be able to tell which end was towards the top and which towards the back though, not so easy on some carved backs.
On a flatback it's obviously rather easy ;).

I guess another point I'd like to make is that it's not really advisable to set your soundpost yourself if you need to log on to in internet forum to get a basic idea of where it needs to be positioned. I wouldn't feel right giving that advice, and I think a lot of the people who responded feel the same.

:D

Back in the day when I started working on my first DB project, that's just how I did it :).
In all fairness though, I had absolutely no-one to turn to regarding advice or the proper techniques.

Granted, it was just a carved 1/2 CCB, but with a few days of searching on the 'net, I was able to not only set the soundpost, but to buy and fit the bridge as well.
Took a full day IIRC to do 'em both.

The feller who bought it from me not long after I finished the repairs, couldn't believe that it really was my first attempt at those tasks.
He did admit that it wasn't perfect by his standards, but unless he had the time to tweak it a bit, good enough as-is for the student of his he bought it for.


That story is by no means an encouragement for the OP or anyone else to just start tinkering with their valuable instrument(s), I've been woodworking since the age of 7 or so and my "first victims" on anything have always been on the cheap end of the spectrum.

So once again, do not ruin anything valuable by attemptig a DIY job.

Regards
Sam
