So, on my upright, I've got this seam between the base of the heel and the body of the instrument (indicated in the picture with a red arrow - don't have pictures at the moment). The bass has held up well since I got it about a year and a half ago, and I can't help but feel this seam is slowly separating. There is no breakage; it is as through the glue used has given a bit of its strength away and has been ever-so-slightly resigned to the tension of the strings. There is a crack in the finish along the seam between the heel, but it's tiny and rather unnoticeable unless looked for closely. Now, when I mean slowly, I mean slowly; I can barely fit the corner of a piece of paper into it now at its absolute widest gap. I could not do that a year ago. The rest of the heel is still firmly attached. I'm wondering how much of an issue it is and am concerned since this is not only my only upright, but I am a young soul who does not have a huge amount of disposable money. Getting the instrument in the first place was an investment, even though the thing "only" was $600 USD (yes, a cheap Chinese bass is better than absolutely nothing otherwise). Is this a normal occurrence? Can it be fixed now instead of later?
