Double Bass seasonal soundposts...

[groooooove]

this may be a dumb question..

i know that our strings get raised when the humidity/heat are higher.

do our sound posts get more tight, or more loose, when humidity is high?

more curious than actually considering two sound posts. seems logical that the top and back would swell, tightening the post.

Yes, soundpost tension changes with humidity. This is why I have an Anima Nova in my English bass. If you have a great luthier nearby you can use two posts. Mine is a 24hr drive away, so a A.N. it is.
It fell while changing strings on friday and I reset it using just my fingers and a tool to knock the base around. It took 10 minutes to get it out of the bass and five to set. Need to get a grabber tool.

Tops rise with increasing humidity and your bass may require a longer post. In dry seasons, the top contracts and a shorter post to fit is necessary. A too long post with a shrinking top may produce a soundpost crack, a major repair that devalues modern basses particularly. I have 4 posts I've collected over the years and change them out spring and winter in Chicago.

Do you change them out yourself or have a luthier/pro do it?

I have a luthier do it.

I have a luthier do it.

Thanks. I’d love to learn how to do it but I’m not going to risk trying it on my own. My guy is 15 minutes away and works out of his house.

Maybe your guy would teach you? I got a lesson at one point, tried to do it and decided to stick with a pro.
