I'm with Treewind on this one.

If the soundpost is in, if there are no obvious flaws (big cracks etc.) and ungluing then string it and play it lots.

I have a £1K value fiddle with a warped neck and fingerboard that sounds good. It has volume but not so hot on the tone. I used to play it for Morris but now my nephew plays it in a school orchestra.

String it - carefully - play it.

Make sure the bridge is well fitted and positioned correctly, this cna ruin tone, hopefully if it has been used there will be feet marks so it is just a case of fitting. If you need advice give me a pm or find a competent luthier - they will usually help on things like this for free (but not always)

And yes where is here?
