Double Bass Wavy Top

[that one guy]

hi everyone,

i have an old japanese made plywood from the 60's. it actually has a good dark thump to it for an inexpensive bass, but there is a waviness in the top specifically where the bridge meets the body on the treble side in the f-hole area. it kind of reminds me of a bad bondo repair on an automobile fender. cosmetics aside, is it something i should be concerned about? is there anything i should do about it?

thanks!

Anybody? I’m sure this is not a new phenomena....

Is the sound post standing and in the correct place? If so, has it always been?

Wavy is hard to figure. If it is a hump, the post could be pushing out. If it is a dip, the top could be sinking. It's hard to say really.

yes, it's a dip. the soundpost has been in the same place for the short time that i've owned it.

the "wavy dip" is right above the bridge and extends to the top of the f-hole area.

the soundpost is located about 3/4" below the bridge foot on the treble side. is this about right?
