I saw a flat back bass with cross bracing, similar to that used on Jakstadt's. Upon further inspection, the bass had been repaired, and one or two of the cross braces had been replaced with a verticle brace, a strip of maple I believe, along the center seam. Apparently the center seam split, cracking the cross braces. The top would have to have been taken off to perform this repair. The bass plays well and despite occasional seams split, the owner has had no problems. There are no cracks as a result of the seam splits. Does such a repair that deviates from the original design reduce the value of the bass or are there any problems that one might anticipate from such a repair?
