: I recently saw a device called a post adjuster for the inside post for an upright bass. How much does this influence sound and tone?
The position of the soundpost in your bass has a big effect on the sound and responsiveness of the instrument. Some people talk about how the sound will be brighter and punchier if the post is a closer to the G-string side bridge foot. It always seemed to me that the sound and feel from one string to another can be affected by the placement of the post. Sometimes a bass will rattle from a loose post.
Soundpost adjusters that I'm familiar with are tools that luthiers use to set the post and aren't intended to be used by novices. Correct soundpost placement is a matter of precise accuracy - a few millileters here or there can make all the difference in the world. Also, it has to be really straight and positioned so that the angle that the ends are cut match the curvature of the top and back.
I STRONGLY suggest that you leave this up to a capable luthier unless you really know what you're doing. It's really easy to drop the post entirely and also really easy to get your bass - and your soundpost - all nicked up and scratched.
Worst case - a badly placed post can actually push through the top when the weather changes.
Don't try this at home.
