Hi guys, My double bass has developed a slight opening under the tailpiece in the top. It's not very open (I can't move it at all with my hands) but there's a very slight white-ish line running about 5 inches. I'm happy to repair it and I know how, but I'm playing for my mum's birthday on the 3rd and I can't guarantee that I'd finish it by then. Do you think it'll hold ok until then? If the top does start to split further then I'll take off the strings and fix it, I'm not even sure it hasn't always been there to be completely honest. Thanks in advance, Joe PS I can't get pics now but might be able to tomorrow?
