As someone that has done this before... Unless you feel the finish is impeding the sound I wouldn't refinish. Removing a hard finish from a double bass is very labor intensive and messy, and some times you don't want to know what is underneath.. Also any sanding/ scraping you do can have a impact on the sound and sctructure or your bass if you remove any actual wood. AND as this is a large object it will be much harder to achieve a nice looking Finnish unless you have a lot of experience.
All that said. 13-14ish years later I am still happy with the refine I did to my bass and am thankful to all the helpful threads here on the subject.
